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:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:43474,

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}.
