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). Is a limiting enzyme for plastidic
CC       isoprenoid biosynthesis and essential for chloroplast development (By
CC       similarity). {ECO:0000250}.
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;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250};
CC   -!- COFACTOR:
CC       Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC         Evidence={ECO:0000250};
CC       Note=Binds 1 thiamine pyrophosphate per subunit. {ECO:0000250};
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.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the transketolase family. DXPS subfamily.
CC       {ECO:0000305}.
