    Phenotypes of a mutant

  • impaired growth in minimal medium, reduced activity of enzymes containing FeS cluster [Pubmed|25988368]
  • sensitivity to superoxide (paraquate) stress [Pubmed|25988368]

    • The protein

    Catalyzed reaction/ biological activity

  • UDP-GlcNAc L-malate = GlcNAc(α1→2)L-malate UDP [Pubmed|20308541]; also uses D-malate as a substrate, but with much lower affinity [Pubmed|20308541]

    • Protein family

  • NamA subfamily (according to Swiss-Prot)

    • Effectors of protein activity

  • subject to feedback inhibition by bacillithiol [Pubmed|22569254]

    • Structure
