CC   -!- FUNCTION: Involved in biosynthesis of the thiamine precursor
CC       thiazole. Catalyzes the conversion of NAD and glycine to adenosine
CC       diphosphate 5-(2-hydroxyethyl)-4-methylthiazole-2-carboxylic acid
CC       (ADT), an adenylated thiazole intermediate. The reaction includes
CC       an iron-dependent sulfide transfer from a conserved cysteine
CC       residue of the protein to a thiazole intermediate. The enzyme can
CC       only undergo a single turnover, which suggests it is a suicide
CC       enzyme. May have additional roles in adaptation to various stress
CC       conditions and in DNA damage tolerance. {ECO:0000256|HAMAP-
CC       Rule:MF_03158}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[ADP-thiazole synthase]-L-cysteine + glycine + NAD(+) =
CC         [ADP-thiazole synthase]-dehydroalanine + ADP-5-ethyl-4-
CC         methylthiazole-2-carboxylate + 2 H(+) + 3 H2O + nicotinamide;

CC   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC         Evidence={ECO:0000256|HAMAP-Rule:MF_03158};
CC       Note=Binds 1 Fe cation per subunit. {ECO:0000256|HAMAP-
CC       Rule:MF_03158};
CC   -!- SUBUNIT: Homooctamer. {ECO:0000256|HAMAP-Rule:MF_03158}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03158}.
CC       Nucleus {ECO:0000256|HAMAP-Rule:MF_03158}.
CC   -!- PTM: During the catalytic reaction, a sulfide is transferred from
CC       Cys-217 to a reaction intermediate, generating a dehydroalanine
CC       residue. {ECO:0000256|HAMAP-Rule:MF_03158}.
CC   -!- SIMILARITY: Belongs to the THI4 family. {ECO:0000256|HAMAP-
CC       Rule:MF_03158}.
