Superfamily Aldolase class I
Functional Family Pyridoxine biosynthesis protein PDX1

Enzyme Information

4.3.3.6
Pyridoxal 5'-phosphate synthase (glutamine hydrolyzing).
based on mapping to UniProt P37527
D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + L-glutamine = pyridoxal 5'-phosphate + L-glutamate + 3 H(2)O + phosphate.
-!- The ammonia is provided by the glutaminase subunit and channeled to the active site of the lyase subunit by a 100 A tunnel. -!- The enzyme can also use ribulose 5-phosphate and dihydroxyacetone phosphate. -!- The enzyme complex is found in aerobic bacteria, archeae, fungi and plants.
