evolution
the Drosophila melanogaster genome contains four low molecular weight protein tyrosine phosphatase (LMW-PTP) members: Primo-1, Primo-2, CG14297, and CG31469 (DARP)
additional information
the enzyme protein adopts the typical LMW-PTP fold and has a canonically arranged P-loop, crystal structure analysis. CG31469 is unique as it contains a threonine residue at the fifth position of the P-loop motif instead of highly conserved isoleucine and a characteristically narrow active site pocket, which should facilitate the accommodation of phosphoarginine. CG31469 is enzymatically active on phosphoarginine. The catalytic motif of DARP is composed of C7IGNTCR13 and is located at the beta1-alpha1 loop, which is called the phosphate-binding loop or simply P-loop. The P-loop motif contains the catalytic serine, which functions as a nucleophile, and the conserved arginine residue (Arg13 in DARP), which anchors the phosphate group of the substrate during dephosphorylation, structural analysis of the catalytic pocket, catalytic loop arrangement and substrate binding, overview. DARP has a characteristically narrow catalytic pocket compared to that of low molecular weight-protein tyrosine phosphatases (LMW-PTPs). The accessibility of the catalytic pocket region, which is controlled by the presence of nonconserved threonine in the P-loop region and the pocket size, determines the substrate preference of DARP. The threonine residue at position 5 of the P-loop significantly contributes to the substrate specificity of DARP. DARP is a cysteine-based phosphatase
malfunction

-
enzyme inactivation significantly decreases the capacity of the mutant to degrade extracellular DNA, to hydrolyze proteins in the extracellular milieu, and to withstand Triton X-100 induced autolysis. Enzyme-deficient mutant cells are additionally ingested faster by polymorphonuclear leukocytes in a whole blood phagocytosis assay

physiological function

a mutant lacking the YwlE arginine phosphatase accumulates a strikingly large number of arginine phosphorylations i.e. 217 sites in 134 proteins, however only a minor fraction of these sites is increasingly modified during heat shock or oxidative stress. The main proteins accumulating comprise central factors of the stress response system including the CtsR and HrcA heat shock repressors, as well as major components of the protein quality control system such as the ClpCP protease and the GroEL chaperonine
physiological function
-
an enzyme deletion strain accumulates arginine phosphorylated proteins and allows for identification of 121 phosphorylation sites for 87 proteins. Protein arginine phosphorylation has a functional role and is involved in the regulation of many critical cellular processes, such as protein degradation, motility, competence, and stringent and stress responses
physiological function
-
during germination, the enzyme (YwlE) dephosphorylates an Arg site on the ribosome associated chaperone Tig, enabling its association with the ribosome to reestablish translation. Arg dephosphorylation of the housekeeping sigma factor A (SigA), mediated by the enzyme (YwlE), facilitates germination by activating the transcriptional machinery
physiological function
-
the enzyme negatively regulates arginine phosphorylation and consequently induces the expression of stress-response genes that are crucial for bacterial stress tolerance and pathogenic homolog Staphylococcus aureus virulence
physiological function
-
the enzyme contributes positively to the ability of Staphylococcus aureus to evade host innate immunity. The enzyme promotes the transcription and secretion of nuclease, the transcription of the aureolysin encoding gene, and reduces the autolytic activity of Staphylococcus aureus

C7S
site-directed mutagenesis, inactive mutant
T11I
site-directed mutagenesis, substitution of Thr11 to isoleucine causes a remarkable decrease in the dephosphorylation of phosphoarginine and a noticeable increase in the dephosphorylation of phosphotyrosine
T11I/Y127F
site-directed mutagenesis, the dephosphorylation activity of the double mutant T11I/Y127F toward phosphotyrosine is noticeably higher than that of the T11I single mutant protein
Y127F
site-directed mutagenesis, the mutation abrogates the hydrogen bond between Tyr127 and Asn44, the Y127F mutant is slightly less active on phosphotyrosine than the wild-type enzyme
C14S
mutation of auxiliary cysteine residue present in the active site, significant resuction in kcat value
C7S
structure in complex with phosphate shows the formation of a covalent phospho-Ser7 adduct indicating that the crystallized mutant mimics the phospho-enzyme intermediate of the dephosphorylation reaction
C9S
