    Phenotypes of a mutant

  • sporulation defect (50-fold reduction of viable spore count) and arrest after engulfment [Pubmed|21037003]
  • The protein

    Catalyzed reaction/ biological activity

  • binding of Fin to the [protein|BC8B37355E6FADBA5F4636C3879E99003B0F3E84|ß'] subunit of [SW|RNA polymerase] prevents binding of [protein|CFF318EE6CACDEE763FBF96A2ABB46E944679AAA|SigF], and thus [protein|CFF318EE6CACDEE763FBF96A2ABB46E944679AAA|SigF]-dependent transcription [pubmed|28598017]
  • Structure

  • [PDB|5MSL] [pubmed|28598017]
  • [SW|Localization]

  • localizes diffusely within the forespore compartment of sporangia at both early and late stages of sporulation, cytosolic protein [Pubmed|21037003]
