This gene is a member of the following regulons

The gene

Basic information

  • Locus tag: BSU27600

Phenotypes of a mutant

  • requirement for valine PubMed
  • a relA sasA sasB triple mutant requires branched chain amino acids, methionine and threonine for growth, the requirement can be suppressed by reduced expression of guaB or inactivation of codY PubMed
  • a relA sasA sasB triple mutant acquires suppressor mutations in guaA, guaB, gmk or inactivation of codY PubMed
  • mutation in relA results in increased motility and chaining PubMed
  • relA mutation increases flagellin production via elevated SigD level PubMed

Database entries

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

Additional information

The protein
