Enzyme Information

2.4.2.60
Cysteine-dependent adenosine diphosphate thiazole synthase.
based on mapping to UniProt Q38814
NAD(+) + glycine + [ADP-thiazole synthase]-L-cysteine = nicotinamide + ADP-5-ethyl-4-methylthiazole-2-carboxylate + [ADP-thiazole synthase]- dehydroalanine + 3 H(2)O.
-!- This iron dependent enzyme, found in fungi, plants, and some archaea, is involved in the thiamine phosphate biosynthesis pathway. -!- It is a single turn-over enzyme since the cysteine residue is not regenerated in vivo. -!- The homologous enzyme in archaea (EC 2.4.2.59) uses sulfide as sulfur donor.
