CC -!- FUNCTION: Catalyzes the formation of pyridoxal 5'-phosphate from ribose
CC 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The
CC ammonia is provided by the PdxT subunit. Can also use ribulose 5-
CC phosphate and dihydroxyacetone phosphate as substrates, resulting from
CC enzyme-catalyzed isomerization of RBP and G3P, respectively.
CC {ECO:0000255|HAMAP-Rule:MF_01824}.
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:58273, ChEBI:CHEBI:58359, ChEBI:CHEBI:59776,
CC ChEBI:CHEBI:597326; EC=4.3.3.6; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01824};
CC -!- PATHWAY: Cofactor biosynthesis; pyridoxal 5'-phosphate biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_01824}.
CC -!- SUBUNIT: In the presence of PdxT, forms a dodecamer of heterodimers.
CC {ECO:0000255|HAMAP-Rule:MF_01824}.
CC -!- SIMILARITY: Belongs to the PdxS/SNZ family. {ECO:0000255|HAMAP-
CC Rule:MF_01824}.
