    • Gene

    Coordinates on the chromosome (coding sequence)
    4,012,866 -> 4,013,699

    Phenotypes of a mutant

  • no expression of the ''[protein|search|bglP]-[protein|search|bglH]'' operon

    • The protein

    Catalyzed reaction/ biological activity

  • binding to the mRNAs of ''[protein|search|bglS]'' and the ''[protein|search|bglP]-[protein|search|bglH]'' operon, causes transcription antitermination (in presence of salicin and absence of glucose)

    • Protein family

  • [[PRD-containing transcription factors]] BglG family of antiterminators (according to Swiss-Prot)

    • Paralogous protein(s)

  • [protein|search|SacY], [protein|search|GlcT], [protein|search|SacT]

    • [SW|Domains]

  • N-terminal RNA binding domain [Pubmed|10610766]
  • 2 x [SW|PRD] ([SW|PTS] regulation domains) [Pubmed|11447120]

    • Modification

  • phosphorylation at His-100 in [SW|PRD]-1 by phosphorylated [protein|search|BglP], inhibits LicT antitermination activity
  • phosphorylation at His-207 and/or His-269 in [SW|PRD]-2 by His-P-[ptsH|search|HPr], stimulates LicT antitermination activity
