Enzyme Information

2.3.1.234

N(6)-L-threonylcarbamoyladenine synthase.

based on mapping to UniProt Q9UXT7

L-threonylcarbamoyladenylate + adenine(37) in tRNA = AMP + N(6)-L- threonylcarbamoyladenine(37) in tRNA.

-!- The enzyme is involved in the synthesis of N(6)- threonylcarbamoyladenosine(37) in tRNAs, which is found in tRNAs with the anticodon NNU, i.e. tRNA(Ile), tRNA(Thr), tRNA(Asn), tRNA(Lys), tRNA(Ser) and tRNA(Arg). -!- Formerly EC 2.6.99.4.
