Enzyme Information

2.7.7.87

L-threonylcarbamoyladenylate synthase.

based on mapping to UniProt Q970S6

L-threonine + ATP + HCO(3)(-) = L-threonylcarbamoyladenylate + diphosphate + H(2)O.

-!- The enzyme is involved in the synthesis of N(6)- threonylcarbamoyladenosine(37) in tRNAs with the anticodon NNU, i.e. tRNA(Ile), tRNA(Thr), tRNA(Asn), tRNA(Lys), tRNA(Ser) and tRNA(Arg).
