Function
function
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.
Catalytic activity
- L-threonylcarbamoyladenylate + adenosine37 in tRNA = N6-L-threonylcarbamoyladenosine37 in tRNA + AMP + H+
Cofactor
Note: Binds 1 Fe2+ ion per subunit.
