Enzyme Information
| 2.3.1.234 |
N(6)-L-threonylcarbamoyladenine synthase.
based on mapping to UniProt Q58530
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.
|
| 2.7.11.1 |
Non-specific serine/threonine protein kinase.
based on mapping to UniProt Q58530
ATP + a protein = ADP + a phosphoprotein.
-!- This is a heterogeneous group of serine/threonine protein kinases that do not have an activating compound and are either non-specific or their specificity has not been analyzed to date. -!- Formerly EC 2.7.1.37 and EC 2.7.1.70.
