ywlC

Gene
ywlC
Protein
Threonylcarbamoyl-AMP synthase
Organism
Bacillus subtilis (strain 168)
Length
346 amino acids
Function
Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Catalyzes the conversion of L-threonine, HCO(3)(-)/CO(2) and ATP to give threonylcarbamoyl-AMP (TC-AMP) as the acyladenylate intermediate, with the release of diphosphate. Is also able to catalyze the reverse reaction in vitro, i.e. the formation of ATP from TC-AMP and PPi.
Similarity
Belongs to the SUA5 family.
