Contents
1-deoxy-D-xylulose 5-phosphate + 3-amino-2-oxopropyl phosphateThus, the two substrates of this enzyme are 1-deoxy-D-xylulose 5-phosphate and 3-amino-2-oxopropyl phosphate, whereas its 3 products are pyridoxine 5'-phosphate, phosphate, and H2O.
Classification
This enzyme belongs to the family of transferases, specifically those transferring nitrogenous groups transferring other nitrogenous groups.
Nomenclature
The systematic name of this enzyme class is 1-deoxy-D-xylulose-5-phosphate:3-amino-2-oxopropyl phosphate 3-amino-2-oxopropyltransferase (phosphate-hydrolysing; cyclizing). Other names in common use include pyridoxine 5-phosphate phospho lyase, PNP synthase, and PdxJ.
Biological role
This enzyme participates in vitamin B6 metabolism.
