CC -!- FUNCTION: Catalyzes the acyloin condensation reaction between C atoms 2
CC and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D-
CC xylulose-5-phosphate (DXP). {ECO:0000255|HAMAP-Rule:MF_00315}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glyceraldehyde 3-phosphate + H(+) + pyruvate = 1-deoxy-D-
CC xylulose 5-phosphate + CO2; Xref=Rhea:RHEA:12605, ChEBI:CHEBI:15361,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57792,
CC ChEBI:CHEBI:59776; EC=2.2.1.7; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00315};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00315};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00315};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00315};
CC Note=Binds 1 thiamine pyrophosphate per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00315};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; 1-deoxy-D-xylulose 5-
CC phosphate biosynthesis; 1-deoxy-D-xylulose 5-phosphate from D-
CC glyceraldehyde 3-phosphate and pyruvate: step 1/1. {ECO:0000255|HAMAP-
CC Rule:MF_00315}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00315}.
CC -!- SIMILARITY: Belongs to the transketolase family. DXPS subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00315}.
