ENZYME entry: EC 2.7.7.73

Accepted Name
Sulfur carrier protein ThiS adenylyltransferase.
Reaction catalysed
ATP + [ThiS] <=> diphosphate + adenylyl-[ThiS]
Cofactor(s)
Zn(2+).
Comment(s)
  • The enzyme catalyzes the adenylation of ThiS, a sulfur carrier protein involved in the biosynthesis of thiamine.
  • The enzyme shows significant structural similarity to ubiquitin- activating enzyme.
  • In Escherichia coli, but not in Bacillus subtilis, the enzyme forms a cross link from Cys-184 to the ThiS carboxy terminus (the position that is also thiolated) via an acyldisulfide.
  • Formerly EC 2.7.7.n3.
