Protein

tRNA N6-adenosine threonylcarbamoyltransferase

Gene

tsaD

Organism
Streptomyces coelicolor (strain ATCC BAA-471 / A3(2) / M145)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t6A37) in tRNAs that read codons beginning with adenine. Is involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaE and TsaB. TsaD likely plays a direct catalytic role in this reaction.UniRule annotation

Catalytic activityi

L-threonylcarbamoyladenylate + adenine(37) in tRNA = AMP + N6-L-threonylcarbamoyladenine(37) in tRNA.UniRule annotation
