The gene

Basic information

  • Locus tag: BSU35500

Phenotypes of a mutant

  • the mutation suppresses the mucoid phenotype of motA or motB mutants due to loss of DegU phosphorylation and concomitant reduced expression of the capB-capC-capA-capE operon PubMed

Database entries

  • DBTBS entry: [1]
  • SubtiList entry: [2]

Additional information

The protein
