ATP + L-tryptophan + tRNATrp = AMP + diphosphate + L-tryptophyl-tRNATrp
a nested, nonlinear model for the sum of metal-free and metal-catalyzed activities and its use in determining metal-free enzyme activity jointly with transition-state metal binding affinity is described, by fitting observed values obtained from Mg2+-depleted assays with increasing EDTA concentrations at known Mg2+ concentrations. Trp activation by TrpRS falls asymptotically to a plateau value 5 orders of magnitude below that observed for the Mg2+-supplemented enzyme at EDTA concentrations that reduce the free metal concentration to below 1 pmolar. The fitted regression model parameters yield a relative rate acceleration of 93000 attributable to the catalytic effect of Mg2+ and an enhanced transition state binding of Mg2+. Factorial analysis indicates that 80% of the reduction in free energy of activation effected by TrpRS arises from protein-ligand interactions
-
ATP + L-tryptophan + tRNATrp = AMP + diphosphate + L-tryptophyl-tRNATrp
recognition of Trp is by an induced-fit mechanism involving conformational change of the AIDQ motif that creates a perfect pocket for the binding and activation of Trp and causes coupled movements of the N-terminal and C-terminal domains. The KMSAS loop has an inherent flexibility and binding of ATP stabilizes it in a closed conformation that secures the position of ATP for catalysis. Structural data indicate that the catalytic mechanism of the Trp activation reaction by hTrpRS involves more moderate conformational changes of the structural elements at the active site compared to bacterial TrpRS

bovine tRNATrp substrate, a two step reaction, the tryptophanyl-tRNA synthetase is a class I amino acid tRNA-synthetase, that catalyzes tryptophan activation in the absence of its cognate tRNA, cognate tRNA is not obligatory to catalyze amino acid activation, the integrated 3’ end of the tRNA is necessary to activate the ATP-diphosphate exchange reaction, overview

ATP + L-tryptophan + tRNATrp
AMP + diphosphate + L-tryptophanyl-tRNATrp
tRNA substrate from Bos taurus, a two step reaction: the amino acid is first activated by ATP to form an aminoacyl-AMP, which is then transferred to the 3' end of the cognate tRNA to form an aminoacyl-tRNA, the discriminator base A73 of the tRNA is specifically recognized by an alpha-helix of the unique N-terminal domain and the anticodon loop by an alpha-helix insertion of the C-terminal domain, the N-terminal domain is involved in Trp activation, but is not essential for tRNA binding and acylation, tryptophan, anticodon, and acceptor arm recognition mechanisms, overview

tRNA substrate from Bos taurus, tryptophan binding pocket structure, overview, two distinct tRNA conformations: uncharged tRNA is bound across the dimer, with anticodon and acceptor stem interacting with separate subunits, in this cross-dimer tRNA complex, the class I enzyme has a class II-like tRNA binding mode, the aminoacylated tRNA is bound only by the anticodon, the acceptor stem being free and having space to interact precisely with EF-1a, suggesting that the product of aminoacylation can be directly handed off to EF-1alpha for the next step of protein synthesis, recognition mechanisms, overview

both TrpRS1 and TrpRS2 are essential for growth and required for cytosolic and mitochondrial tryptophanyl-tRNA formation, respectively, the edited anticodon and the mitochondria-specific thiolation of U33 in the imported tRNATrp act as antideterminants for the cytosolic TrpRS1, the mitochondrion of Trypanosoma brucei does not encode any tRNAs, this deficiency is compensated for by the import of a small fraction of nearly all of its cytosolic tRNAs from the host

CAS: 63339-68-4, natural product, first isolated from Actinoplanes tsinanensis, potent and selective inhibition of the aminoacylation
indolmycin
competitive inhibitor, produced by Streptomyces griseus, causes selective, mechanism-based inhibition of the bacterial enzyme, which preferentially binds indolmycin about 1500fold more tightly than its tryptophan substrate, binding structure analysis overview. Long range coupling to residues within an allosteric region called the D1 switch of BsTrpRS positions the Mg2+ ion in a manner that allows it to assist in transition state stabilization. The Mg2+ ion in the inhibited complex forms significantly closer contacts with non-bridging oxygen atoms from each phosphate group of ATP and three water molecules than occur in the (presumably catalytically competent) pre-transition state (preTS) crystal structures. This altered coordination stabilizes a ground state Mg2+-ATP-configuration, accounting for the high affinity inhibition of BsTrpRS by indolmycin
