Gene
Coordinates
19,062 19,946
Phenotypes of a mutant
the mutant tends to acquire suppressor mutations that result in improved growth and colony morphology [Pubmed|28189581]
auxotrophic for pyridoxal 5'-phosphate [Pubmed|14762015]
inactivation of [gene|651D1E534490276B9BE7BFE7B5819176AE09891E|pdxS] reduces sporulation efficiency to 1.2% that of wild type cells [Pubmed|26735940]
poor growth [pubmed|28189581]
non-transformable [pubmed|28189581]
The protein
Catalyzed reaction/ biological activity
Catalyzes the formation of pyridoxal 5'-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by the [protein|6F96C10759C1C20B3A6B396E3718F0A9281F100A|pdxT] subunit. (according to UniProt)
aldehydo-D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + L-glutamine --> H+ + 3 H2O + L-glutamate + phosphate + pyridoxal 5'-phosphate (according to UniProt)
Protein family
PdxS/SNZ family (single member, according to UniProt)
