yeast mitochondrial threonyl-tRNA synthetase MST1 lacks an editing domain and utilizes pre-transfer editing to discriminate against serine. MST1 misactivates serine and edits seryl adenylate (Ser-AMP) in the absence of the cognate tRNA. MST1 hydrolyzes 80% of misactivated Ser-AMP at a rate 4fold higher than that for the cognate threonyl adenylate (Thr-AMP) while releasing 20% of Ser-AMP into the solution.

for cognate threonine, amino acid activation is likely to be the rate-limiting step. The inability of wild-type ThrRS to prevent utilization of beta-hydroxynorvaline as a substrate illustrates that the naturally occurring enzyme lacks the capability to effectively discriminate against nonproteogenic amino acids that are not encountered under normal physiological conditions

Escherichia coli threonine tRNA is not aminoacylated by the Haloferax volcanii enzyme. The Escherichia coli mutant tRNAThr having U73 is threonylated by the Haloferax volcanii enzyme. The discriminator base U73 of Haloferax volcanii tRNAThr is a strong determinant for the recognition by threonyl-tRNA synthetase

in the pre-steady state, asymmetric activation of cognate threonine and noncognate serine is observed in the active sites of dimeric ThrRS, with similar rates of activation. In the absence of tRNA, seryl-adenylate is hydrolyzed 29old faster by the ThrRS catalytic domain than threonyl-adenylate. The rate of seryl transfer to cognate tRNA is only 2fold slower than threonine

proofreading modules of aminoacyl-tRNA synthetases are responsible for enforcing a high fidelity during translation of the genetic code. They use strategically positioned side chains for specifically targeting incorrect aminoacyl-tRNAs. A unique proofreading module possessing a D-aminoacyl-tRNA deacylase fold does not use side chains for imparting specificity or for catalysis, the two hallmark activities of enzymes

yeast mitochondrial threonyl-tRNA synthetase MST1 lacks an editing domain and utilizes pre-transfer editing to discriminate against serine. MST1 misactivates serine and edits seryl adenylate (Ser-AMP) in the absence of the cognate tRNA. MST1 hydrolyzes 80% of misactivated Ser-AMP at a rate 4fold higher than that for the cognate threonyl adenylate (Thr-AMP) while releasing 20% of Ser-AMP into the solution.

H2O2
oxidation of ThrRS by H2O2 causes editing defects and Ser misincorporation at Thr codons due to oxidation of Cys182, zinc or nickel ions inhibit C182 oxidation by hydrogen peroxide. Reducing the oxidized ThrRS with DTT or sodium arsenite (NaAsO2) recovers the editing activity, cysteine residue C182 is reversibly oxidized
hydrogen peroxide
-
oxidizes cysteine182 residue critical for editing, which leads to Ser-tRNAThr formation and protein mistranslation that impaired growth of Escherichia coli. Presence of major heat shock proteases is required to allow cell growth in medium containing serine and hydrogen peroxide, which suggests that the mistranslated proteins are misfolded

borrelidin
is an 18-membered macrolide polyketide produced by several actinomycete bacteria of the Streptomyces spp.. Identification of borrelidin binding site on threonyl-tRNA synthetase, molecular docking, overview. Borrelidin binds the pocket outside but adjacent to the active site of ThrRS, consisting of residues Y313, R363, R375, P424, E458, G459, and K465. Borrelidin may induce the cleft closure, which blocks the release of Thr-AMP and phosphate, to inhibit activity of ThrRS rather than inhibit the binding of ATP and threonine
