CC -!- FUNCTION: Involved in biosynthesis of the thiamine precursor thiazole.
CC Catalyzes the conversion of NAD and glycine to adenosine diphosphate 5-
CC (2-hydroxyethyl)-4-methylthiazole-2-carboxylic acid (ADT), an
CC adenylated thiazole intermediate. The reaction includes an iron-
CC dependent sulfide transfer from a conserved cysteine residue of the
CC protein to a thiazole intermediate. The enzyme can only undergo a
CC single turnover, which suggests it is a suicide enzyme. May have
CC additional roles in adaptation to various stress conditions and in DNA
CC damage tolerance. {ECO:0000256|HAMAP-Rule:MF_03158}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[ADP-thiazole synthase]-L-cysteine + glycine + NAD(+) = [ADP-
CC thiazole synthase]-dehydroalanine + ADP-5-ethyl-4-methylthiazole-2-
CC carboxylate + 2 H(+) + 3 H2O + nicotinamide; Xref=Rhea:RHEA:55708,

CC ChEBI:CHEBI:139151; EC=2.4.2.60; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_03158};
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-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 Cys-
CC 216 to a reaction intermediate, generating a dehydroalanine residue.
CC {ECO:0000256|HAMAP-Rule:MF_03158}.
CC -!- SIMILARITY: Belongs to the THI4 family. {ECO:0000256|HAMAP-
CC Rule:MF_03158}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
