ATP + [prokaryotic ubiquitin-like protein]-L-glutamate + [protein]-L-lysine = ADP + phosphate + N6-([prokaryotic ubiquitin-like protein]-gamma-L-glutamyl)-[protein]-L-lysine
PafA catalyzes a two-step reaction by forming a gamma-glutamyl phosphate-mixed anhydride intermediate on the C-terminal glutamate of PupE by hydrolyzing ATP, followed by attaching it to nucleophilic substrates by catalyzing the formation of isopeptide bonds between PupE C-terminal glutamate gamma-carboxylate and the side chain of protein substrate lysine residues, mechanism of PafA self-pupylation, overview. K320 is the major target residue for the pupylation of PafA. During the self-pupylation of PafA, the attachment of the first Pup to PafA is catalyzed by the other PafA molecule through an intermolecular reaction, while the formation of the polymeric Pup chain is carried out in an intramolecular manner through the internal ligase activity of the already pupylated PafA. Among the three lysine residues, K7, K31 and K61, in Mycobacterium smegmatis Pup, K7 and K31 are involved in the formation of the poly-Pup chain in PafA poly-pupylation. Poly-pupylation of PafA can be reversibly regulated by depupylase Dop

pupylation is a signal for proteasomal degradation in bacteria. The prokaryotic, ubiquitin-like protein (Pup) is conjugated through its C-terminal residue to lysine side chains of substrates via an isopeptide bond. Pup proteins are small, ranging from 60 to 70 residues in length with Gly-Gly-Glu or Gly-Gly-Gln as C-terminal residues. Deamidation of the C-terminal glutamine of Pup by the deamidase of Pup (Dop) renders Pup competent for conjugation to substrates, which is then carried out by the Pup-ligase PafA

PafA is an allosteric enzyme that binds its target substrates cooperatively. In contrast, binding of deamidated Pup (Pup-L-glutamate) by PafA follows simple kinetics and is, therefore, not involved in the allosteric transitions of PafA. Pup and target substrate binding by PafA are independent events

Pup proteins are small, ranging from 60 to 70 residues in length with Gly-Gly-Glu or Gly-Gly-Gln as C-terminal residues. Deamidation of the C-terminal glutamine of Pup by the deamidase of Pup (Dop) renders Pup competent for conjugation to substrates, which is then carried out by the Pup-ligase PafA. The enzyme turns over one molecule of ATP to ADP per conjugation cycle, suggesting that PafA activates Pup by phosphorylation of its C-terminal glutamate. The formation of this intermediate occurs even in the absence of substrate and is shown to be the rate-limiting step of the PafA catalyzed reaction. After activation, the phosphorylated Pup and ADP remain bound to PafA, awaiting the nucleophilic attack of the substrate lysine, which finally results in the formation of the isopeptide bond. The C-terminal residue of the ligation-competent PupE features two carboxylates, the C-terminal alpha-carboxylate and the gamma-carboxylate of the glutamyl side chain, both of which could in principle be used for Pup-attachment. NMR-experiments using the pupylated proteasomal substrate PanB show that only the gamma-carboxylate is used to form the isopeptide bond between Pup and the target

PafA substrate docking study, overview. PafA can use ammoniumions as targets for pupylation. The reaction catalyzed is in fact the conversion of PupE C-terminal glutamate into a glutamine, that is, PupE amidation. The docking of a small molecule like ammonium in the PafA active site cannot be supported by auxiliary interactions. PafA residue R207 stabilizes the interaction of the enzyme with PanB, the R207A mutant amidates PupE and the wild-type variant

PafA can move Pup from one proteasome substrate, inositol 1-phosphate synthetase (Ino1), to two different proteins, malonyl coenzyme A (CoA)-acyl carrier protein transacylase (FabD) and lonely guy (Log). Mutagenesis of substrate FabD Lys173 to Ala results in reduced transfer of Pup from Pup-Ino1 in the transpupylation reaction. Pup-Ino1 is a better Pup donor than Pup-FabD, and transpupylation requires ATP. PafA needs depupylase activity to transfer Pup between proteins. Pupylation is a two-step reaction in which PafA uses ATP to phosphorylate a carboxylate on the C terminus of Pup, which is then attacked by the amino group of a lysine side chain

the prokaryotic ubiquitin-like protein remains intrinsically disordered when covalently attached to proteasomal target proteins. When linked to the proteasomal substrates FabD and PanB, Pup is unstructured and retains the ability to interact with its different binding partners. This suggests that it is not the conformation of Pup attached to these two substrates which determines their delivery to the proteasome, but the availability of the degradation complex and the depupylase. Structure analysis of Pup coupled to the PanB decamer, overview

PafA can pupylate itself, extra-pupylation by PafA can also occur, mostly in the form of poly-pupylation. Unlike in the eukaryotic UPS where poly-ubiquitylation is seen, in vivo targets of the Pup-proteasome system are found almost exclusively to be monopupylated, except for PafA itself. Poly-pupylation occurs via pupylation of an already pupylated target, rather than by conjugation of pre-formed poly-Pup chains

PafA self-pupylation is suppressed when PanB is added at high concentrations. Unlike the pattern of poly-pupylated PafA, only mono-pupylated PanB and a few di-pupylated PanB (Pup2-PanB) can be detected in the reaction system

pupylation of proteasome-interacting ATPase (Mpa) occurs predominantly on one target lysine. Pupylation at this position prevents interaction of Mpa/prokaryotic ubiquitin-like protein(Pup) with the proteasome core. Ultimately, pupylation leads to deoligomerization of the Mpa hexamer driven by the unfolding activity of Mpa, thereby rendering Mpa-Pup fully inactive

pupylation is a signal for proteasomal degradation in bacteria. The prokaryotic, ubiquitin-like protein (Pup) is conjugated through its C-terminal residue to lysine side chains of substrates via an isopeptide bond. Pup proteins are small, ranging from 60 to 70 residues in length with Gly-Gly-Glu or Gly-Gly-Gln as C-terminal residues. Deamidation of the C-terminal glutamine of Pup by the deamidase of Pup (Dop) renders Pup competent for conjugation to substrates, which is then carried out by the Pup-ligase PafA

metabolism
prokaryotic ubiquitin-like protein (Pup) is a post-translational modifier that attaches to more than 50 proteins in Mycobacteria. Proteasome accessory factor A (PafA) is responsible for Pup conjugation to substrates
metabolism
-
proteasome-containing bacteria possess a tagging system that directs proteins to proteasomal degradation by conjugating them to a prokaryotic ubiquitin-like protein (Pup). A single ligating enzyme, PafA, is responsible for Pup conjugation to lysine side chains of protein substrates. As Pup is recognized by the regulatory subunit of the proteasome, Pup functions as a degradation tag. Ligating enzyme PafA and the proteasome can function as a modular machine for the tagging and degradation of cytoplasmic proteins
metabolism
pupylation is a bacterial post-translational modification of target proteins on lysine residues with prokaryotic ubiquitinlike protein (Pup). Pup-tagged substrates are recognized by a proteasome-interacting ATPase (Mpa) in Mycobacterium tuberculosis. Mpa unfolds pupylated substrates and threads them into the proteasome core particle for degradation

posttranslational regulation of coordinated enzyme activities in the prokaryotic ubiquitin-like protein (Pup)-proteasome system (PPS), overview. Pup, a ubiquitin analogue, is conjugated to proteins through the activities of two enzymes, Dop (deamidase of Pup) and PafA (proteasome accessory factor A), the Pup ligase. The depupylase activity of Dop counteracts the actions of PafA. tight Pup binding and the limited degree of Dop interaction with high-molecular-weight pupylated proteins results in preferred Pup deamidation over protein depupylation by enzyme Dop. Dop is depleted in the absence of Pup in stationary-phase cells. Pup-PanB and Pup-IdeR act as tight-binding competitors versus Pup binding by Dop. Pup binding stabilizes Dop and prevents its depletion. PafA and Dop generate a high-molecular-weight pupylome

physiological function
in Mycobacterium tuberculosis Pup tagging is important for virulence
physiological function
pupylation is a signal for proteasomal degradation in bacteria. The prokaryotic, ubiquitin-like protein (Pup) is conjugated through its C-terminal residue to lysine side chains of substrates via an isopeptide bond
physiological function
bacteria use an intrinsically disordered protein, Pup, to mark proteins for destruction. The protein degradation machinery of Mycobacterium tuberculosis includes a proteasome and a ubiquitin-like protein (Pup). Proteasome accessory factor A (PafA) attaches Pup to proteins to target them for degradation by the proteasome. PafA can move Pup from one proteasome substrate, inositol 1-phosphate synthetase (Ino1), to two different proteins, malonyl coenzyme A (CoA)-acyl carrier protein transacylase (FabD) and lonely guy (Log). This apparent transpupylation reaction requires a previously unrecognized depupylase activity in PafA, and, surprisingly, this depupylase activity is much more efficient than the activity of the dedicated depupylase Dop (deamidase of Pup). Thus, PafA can potentially use both newly synthesized Pup and recycled Pup to doom proteins for degradation. In contrast, enzyme Dop, in addition to deamidating PupGln to PupGlu, can remove Pup from proteins, which can rescue them from proteasomal degradation. PafA, unlike Dop, can-not deamidate PupGln to PupGlu, thus, PafA amidase activity appears to be limited to pupylated proteins
physiological function
enzyme PafA, the prokaryotic ubiquitin-like protein (Pup) ligase, catalyzes the Pup modification of bacterial proteins and targets the substrates for proteasomal degradation. Mycobacterium smegmatis PafA can be poly-pupylated. Self-pupylation of PafA is reversely regulated by Dop, a dual-functional enzyme, functioning as deaminase to convert PupQ to PupE and also as depupylase to remove Pup from the pupylated proteins. The self-pupylation of PafA is involved in the regulation of its stability
physiological function
prokaryotic ubiquitin-like protein (Pup) is a small protein that can be covalently attached to lysine side chains of cellular proteins by Pup ligase PafA. Pupylation serves as a recruitment tool for proteasomal degradation. For Mycobacterium tuberculosis, pupylation and the recruitment of pupylated substrates to the proteasome support persistence inside host macrophages during pathogenesis. Pup serves as both recognition and threading element in proteasomal degradation of pupylated substrates. The degradation substrate covalently modified with Pup is recruited to the Mpa-proteasome complex by docking to the Mpa coiled-coil domain, which triggers Pup to undergo a disorder-to-order transition, forming an extended helix that associates into a shared three-stranded coil with the Mpa N-terminal coiled-coil domains. The disordered N-terminal region of Pup points into the Mpa central pore, where it is engaged by the ATPase-driven pore loops for unfolding and directional translocation into the proteasome core for degradation.
