Enzyme Information

3.5.1.2
Glutaminase.
based on mapping to UniProt Q59055
L-glutamine + H(2)O = L-glutamate + NH(3).
4.3.3.6
Pyridoxal 5'-phosphate synthase (glutamine hydrolyzing).
based on mapping to UniProt Q59055
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.
