Protein Family Models

This family contains 1-deoxyxylulose-5-phosphate synthase (DXP synthase), an enzyme which catalyses the thiamine pyrophosphoate-dependent acyloin condensation reaction between carbon atoms 2 and 3 of pyruvate and glyceraldehyde 3-phosphate, to yield 1-deoxy-D- xylulose-5-phosphate, a precursor in the biosynthetic pathway to isoprenoids, thiamine (vitamin B1), and pyridoxol (vitamin B6).

DXP synthase is a thiamine diphosphate-dependent enzyme related to transketolase and the pyruvate dehydrogenase E1-beta subunit. By an acyloin condensation of pyruvate with glyceraldehyde 3-phosphate, it produces 1-deoxy-D-xylulose 5-phosphate, a precursor of thiamine diphosphate (TPP), pyridoxal phosphate, and the isoprenoid building block isopentenyl diphosphate (IPP).
