Entry
Name
sulfur carrier protein ThiS adenylyltransferase;
thiF (gene name)
Class
Transferases;
Transferring phosphorus-containing groups;
Nucleotidyltransferases
BRITE hierarchy
Sysname
ATP:[ThiS] adenylyltransferase
Reaction(IUBMB)
ATP + [ThiS] = diphosphate + adenylyl-[ThiS] [RN:
R07459 ]
Reaction(KEGG)
Substrate
Product
diphosphate [CPD:
C00013 ];
adenylyl-[ThiS]
Comment
Binds Zn2+. The enzyme catalyses the adenylation of ThiS, a sulfur carrier protein involved in the biosynthesis of thiamine.
The enzyme shows significant structural similarity to ubiquitin-activating enzyme [3,4]. 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 [2].
