General annotation (Comments)

Function	Catalyzes the acyloin condensation reaction between C atoms 2 and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D-xylulose-5-phosphate (DXP) By similarity.
Catalytic activity	Pyruvate + D-glyceraldehyde 3-phosphate = 1-deoxy-D-xylulose 5-phosphate + CO(2).
Cofactor	Binds 1 thiamine pyrophosphate per subunit By similarity.
Pathway	Metabolic intermediate biosynthesis; 1-deoxy-D-xylulose 5-phosphate biosynthesis; 1-deoxy-D-xylulose 5-phosphate from D-glyceraldehyde 3-phosphate and pyruvate: step 1/1.
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the transketolase family. DXPS subfamily.
