    Coordinates on the chromosome (coding sequence)
    647,091 -> 647,738

    Phenotypes of a mutant

  • inactivation of ''[SW|rex]'' reduces sporulation efficiency to 9.2% that of wild type cells [Pubmed|26735940]
  • The protein

    Protein family

  • transcriptional regulatory rex family (according to Swiss-Prot)
  • Effectors of protein activity

  • NADH (indication of low oxygen concentration) releases Rex from DNA [Pubmed|18485070], Rex has a very highh affinity for NADH
  • Structure

  • [PDB|2VT2], [PDB|2VT3]
  • [SW|Localization]
