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).

thiamine pyrophosphate-dependent dehydrogenase E1 component subunit alpha is part of the E1 component of a multi-enzyme dehydrogenase complex such as branched-chain alpha-keto acid dehydrogenase, which catalyzes the multi-step oxidative decarboxylation of alpha-keto acids derived from the branched-chain amino-acids valine, leucine, and isoleucine
