    • Gene

    Coordinates on the chromosome (coding sequence)
    2,552,653 -> 2,552,988

    Phenotypes of a mutant

  • the mutation suppresses the galactose toxicity to a'' [protein|search|galE]'' mutant [Pubmed|22893383]

    • The protein

    Catalyzed reaction/ biological activity

  • transcription regulator of biofilm genes, acts as a true repressor of the ''[protein|search|tapA]-[protein|search|sipW]-[protein|search|tasA]'' operon and as an anti-activator (prevents binding of the activator protein [protein|search|RemA]) of the ''[protein|search|epsA]-[protein|search|epsB]-[protein|search|epsC]-[protein|search|epsD]-[protein|search|epsE]-[protein|search|epsF]-[protein|search|epsG]-[protein|search|epsH]-[protein|search|epsI]-[protein|search|epsJ]-[protein|search|epsK]-[protein|search|epsL]-[protein|search|epsM]-[protein|search|epsN]-[protein|search|epsO]'' operon [Pubmed|23646920]
