    Phenotypes of a mutant

  • cells are bent and distended due to the lack of glucolipids [Pubmed|27684739]
  • the inactivation of ''[gene|70412A747D1ED3E885126945DF02503667C13E5B|pgcA]'' suppresses the poor and filamentous growth of the ''[gene|1986DB3078FBA16D6ACCD70EEAC95C46564D0958|whiA] [gene|EAD44AA7D72510B70308FD0C9F159DBEDAEBBB74|zapA]'' double mutant [Pubmed|24097947]
  • inactivation of ''[gene|70412A747D1ED3E885126945DF02503667C13E5B|pgcA]'' reduces sporulation efficiency to 0.1% that of wild type cells; smaller and wider mother cells with small forespores [Pubmed|26735940]
  • resistant to phage SPO1 [pubmed|30811056]
  • a [gene|70412A747D1ED3E885126945DF02503667C13E5B|pgcA] [gene|7150BABA5086D5E2EB8102E4901A216F43576282|glmR] double mutant is not viable, this can be suppressed by overexpression of [protein|F022ACB2CBB8DA46B392CE1D26474093645F26DA|GlmM] [pubmed|31589605]

    • The protein

    Catalyzed reaction/ biological activity

  • α-D-glucose 1-phosphate --> α-D-glucose 6-phosphate (according to UniProt)
  • D-glucosamine 6-phosphate --> α-D-glucosamine 1-phosphate (secondary activity, this activity is increased by a G47S mutation) [pubmed|31589605]

    • Protein family

  • phosphohexose mutase family (with [protein|F022ACB2CBB8DA46B392CE1D26474093645F26DA|GlmM], [pubmed|15238632])

    • Modification

  • phosphorylated on ser/ thr/ tyr [Pubmed|16493705], [Pubmed|17726680]

    • Structure

  • [PDB|2Z0F] (from Thermus thermophilus, 27% identity)

  • a PgcA (G47S) variant suppresses the growth defect of a [gene|7150BABA5086D5E2EB8102E4901A216F43576282|glmR] mutant on gluconeogenic carbon sources in the absence of glucose due to the increased phosphoglucosamine mutase activity [pubmed|31589605]
