    Phenotypes of a mutant

  • 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)

    • Modification

  • phosphorylated on Arg-8 [Pubmed|22517742]
  • phosphorylated on STY [Pubmed|16493705], [Pubmed|17726680]

    • Structure

  • [PDB|2NV2] [protein|651D1E534490276B9BE7BFE7B5819176AE09891E|PdxS]-[protein|6F96C10759C1C20B3A6B396E3718F0A9281F100A|PdxT] complex [Pubmed|17159152]
