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. HAMAP MF_00315

Catalytic activity

Pyruvate + D-glyceraldehyde 3-phosphate = 1-deoxy-D-xylulose 5-phosphate + CO2. HAMAP MF_00315

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. HAMAP MF_00315

Subunit structure

Homodimer By similarity. HAMAP MF_00315

Sequence similarities

Belongs to the transketolase family. DXPS subfamily.
