RT phosphate synthase Snz1.";
RL Biochem. J. 432:445-450(2010).
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 a SNO isoform. Can also use ribulose 5-phosphate
CC and dihydroxyacetone phosphate as substrates, resulting from enzyme-
CC catalyzed isomerization of RBP and G3P, respectively.

CC ECO:0000269|PubMed:19523954}.
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 Evidence={ECO:0000269|PubMed:19523954, ECO:0000269|PubMed:20919991};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.11 mM for ribose 5-phosphate {ECO:0000269|PubMed:19523954};
CC KM=0.3 mM for glyceraldehyde 3-phosphate
CC {ECO:0000269|PubMed:19523954};
CC Vmax=1.45 nmol/min/mg enzyme with ribose 5-phosphate as substrate
CC {ECO:0000269|PubMed:19523954};
CC Vmax=1.54 nmol/min/mg enzyme with glyceraldehyde 3-phosphate as
CC substrate {ECO:0000269|PubMed:19523954};
CC -!- PATHWAY: Cofactor biosynthesis; pyridoxal 5'-phosphate biosynthesis.
CC -!- SUBUNIT: Homohexamer (PubMed:19523954). Interacts with AIM18
CC (PubMed:12271461). {ECO:0000269|PubMed:12271461,
CC ECO:0000269|PubMed:19523954}.
CC -!- INTERACTION:
CC Q03148; Q03144: SNO1; NbExp=4; IntAct=EBI-17618, EBI-28190;
CC -!- DEVELOPMENTAL STAGE: Shows increased synthesis after entry into
CC stationary phase.
CC -!- DISRUPTION PHENOTYPE: Defects cause some sensibility to 6-azauracil, an
CC inhibitor of purine and pyrimidine biosynthetic enzymes, and methylene
CC blue, a producer of singlet oxygen. These effects are probably due to
CC the inability to synthesize pyridoxal 5'-phosphate.
CC {ECO:0000269|PubMed:12271461}.
CC -!- SIMILARITY: Belongs to the PdxS/SNZ family. {ECO:0000305}.
