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).

This family includes transketolase enzymes EC:2.2.1.1. and also partially matches to 2-oxoisovalerate dehydrogenase beta subunit Swiss:P37941 EC:1.2.4.4. Both these enzymes utilise thiamine pyrophosphate as a cofactor, suggesting there may be common aspects in their mechanism of catalysis. [1]. 8176731.

transketolase with the TPP di-phosphate residue-binding domain but lacking the TPP pyrimidine-binding domain and the C-terminal domain; transketolase catalyzes the transfer of a two-carbon unit from ketose phosphates to aldose phosphates
