Pyridoxal 5'-phosphate synthase (glutamine hydrolyzing) (EC 4.3.3.6, PdxST) is an enzyme with systematic name D-ribose 5-phosphate,D-glyceraldehyde 3-phosphate pyridoxal 5'-phosphate-lyase.[1][2][3][4][5][6][7][8] This enzyme catalyses the following chemical reaction
- D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + L-glutamine
pyridoxal 5'-phosphate + L-glutamate + 3 H2O + phosphate (overall reaction) - (1a) L-glutamine + H2O L-glutamate + NH3
- (1b) D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + NH3 pyridoxal 5'-phosphate + 4 H2O + phosphate
The enzyme can also use ribulose 5-phosphate and dihydroxyacetone phosphate.
