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 CC PdxS. {ECO:0000256|HAMAP-Rule:MF_01615}. CC -!- CATALYTIC ACTIVITY: D-ribose 5-phosphate + D-glyceraldehyde 3- CC phosphate + L-glutamine = pyridoxal 5'-phosphate + L-glutamate + 3 CC H(2)O + phosphate. {ECO:0000256|HAMAP-Rule:MF_01615}. CC -!- CATALYTIC ACTIVITY: L-glutamine + H(2)O = L-glutamate + NH(3). CC {ECO:0000256|HAMAP-Rule:MF_01615}. CC -!- PATHWAY: Cofactor biosynthesis; pyridoxal 5'-phosphate CC biosynthesis. {ECO:0000256|HAMAP-Rule:MF_01615}. CC -!- SUBUNIT: In the presence of PdxS, forms a dodecamer of CC heterodimers. Only shows activity in the heterodimer. CC {ECO:0000256|HAMAP-Rule:MF_01615}. CC -!- SIMILARITY: Belongs to the glutaminase PdxT/SNO family. CC {ECO:0000256|HAMAP-Rule:MF_01615}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:ODQ96763.1}.
