    Phenotypes of a mutant

  • the [gene|240CD6EA3793821F5109252BDEF69C0120E454EF|ypqP] mutant of PY79 has a less hydrophobic spore surface [pubmed|32817102]

    • The protein

    Catalyzed reaction/ biological activity

  • SpsM catalyzes the C-4/C-6 dehydration of the UDP-GlcNAc to produce UDP-4-keto-6-deoxy-GlcNAc, this is the first reaction of the legionaminic acid biosynthesis pathway [pubmed|32817102]
  • required for spore crust assembly, legionaminic acid synthesis [pubmed|32817102]
