CC -!- FUNCTION: Catalyzes the hydrolysis of glutamine to glutamate and
CC ammonia as part of the biosynthesis of pyridoxal 5'-phosphate. The
CC resulting ammonia molecule is channeled to the active site of PdxS.
CC {ECO:0000256|HAMAP-Rule:MF_01615}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + L-glutamine = L-glutamate + NH4(+);
CC Xref=Rhea:RHEA:15889, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:29985, ChEBI:CHEBI:58359; EC=3.5.1.2;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01615};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=aldehydo-D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate +
CC L-glutamine = H(+) + 3 H2O + L-glutamate + phosphate + pyridoxal 5'-
CC phosphate; Xref=Rhea:RHEA:31507, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:58273, ChEBI:CHEBI:58359, ChEBI:CHEBI:59776,
CC ChEBI:CHEBI:597326; EC=4.3.3.6; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01615};
CC -!- PATHWAY: Cofactor biosynthesis; pyridoxal 5'-phosphate biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_01615}.
CC -!- SUBUNIT: In the presence of PdxS, forms a dodecamer of heterodimers.
CC Only shows activity in the heterodimer. {ECO:0000256|HAMAP-
CC Rule:MF_01615}.
CC -!- SIMILARITY: Belongs to the glutaminase PdxT/SNO family.
CC {ECO:0000256|ARBA:ARBA00008345, ECO:0000256|HAMAP-Rule:MF_01615}.
