Accepted name: 1-deoxy-D-xylulose-5-phosphate synthase
Reaction: pyruvate + D-glyceraldehyde 3-phosphate = 1-deoxy-D-xylulose 5-phosphate + CO2
Glossary: thiamine diphosphate = 3-[(4-amino-2-methylpyrimidin-5-yl)methyl]-5-(2-diphosphoethyl)-4-methyl-1,3-thiazolium
Other name(s): 1-deoxy-D-xylulose-5-phosphate pyruvate-lyase (carboxylating); DXP-synthase
Systematic name: pyruvate:D-glyceraldehyde-3-phosphate acetaldehydetransferase (decarboxylating)
Comments: Requires thiamine diphosphate. The enzyme forms part of an alternative nonmevalonate pathway for terpenoid biosynthesis (for diagram, click here).
