Accepted name: sulfide-dependent adenosine diphosphate thiazole synthase
Reaction: NAD+ + glycine + sulfide = nicotinamide + ADP-5-ethyl-4-methylthiazole-2-carboxylate + 3 H2O
Other name(s): Thi4 (ambiguous)
Systematic name: NAD+:glycine ADP-D-ribosyltransferase (sulfide-adding)
Comments: This iron dependent enzyme, found in most archaea, is involved in the biosynthesis of thiamine phosphate. The homologous enzyme from plants and fungi (EC, cysteine-dependent adenosine diphosphate thiazole synthase) uses an intrinsic cysteine as sulfur donor and, unlike the archaeal enzyme, is a single turn-over enzyme.
