Threonylcarbamoyl-AMP synthase

source
Escherichia coli str. K-12 substr. MG1655

Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Catalyzes the conversion of L-threonine, HCO(3)(-)/CO(2) and ATP to give threonylcarbamoyl-AMP (TC-AMP) as the acyladenylate intermediate, with the release of diphosphate. Is also able to catalyze the reverse reaction in vitro, i.e. the formation of ATP from TC-AMP and PPi. Shows higher affinity for the full-length tRNA(Thr) lacking only the t(6)A37 modification than for its fully modified counterpart. Could also be required for the maturation of 16S rRNA. Binds to double-stranded RNA but does not interact tightly with either of the ribosomal subunits, or the 70S particles.
