Function
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).
Catalytic activity
- D-glyceraldehyde 3-phosphate + H+ + pyruvate = 1-deoxy-D-xylulose 5-phosphate + CO2
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 Mg2+ ion per subunit.
Note: Binds 1 thiamine pyrophosphate per subunit.
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.
