CC -!- FUNCTION: Catalyzes the rearrangement of 1-deoxy-D-xylulose 5-phosphate
CC (DXP) to produce the thiazole phosphate moiety of thiamine. Sulfur is
CC provided by the thiocarboxylate moiety of the carrier protein ThiS. In
CC vitro, sulfur can be provided by H(2)S. {ECO:0000255|HAMAP-
CC Rule:MF_00443}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1-deoxy-D-xylulose 5-phosphate + 2-iminoacetate + [sulfur-
CC carrier protein ThiS]-C-terminal Gly-NH-CH2-C(O)SH = 2-[(2R,5Z)-2-
CC carboxy-4-methylthiazol-5(2H)-ylidene]ethyl phosphate + [sulfur-
CC carrier protein ThiS]-C-terminal Gly-Gly + 2 H(+) + 2 H2O;

CC ChEBI:CHEBI:90778; EC=2.8.1.10; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00443};
CC -!- PATHWAY: Cofactor biosynthesis; thiamine diphosphate biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00443}.
CC -!- SUBUNIT: Homotetramer. Forms heterodimers with either ThiH or ThiS.
CC {ECO:0000255|HAMAP-Rule:MF_00443}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00443}.
CC -!- SIMILARITY: Belongs to the ThiG family. {ECO:0000255|HAMAP-
CC Rule:MF_00443}.
