The protein

Basic information/ Evolution

• Catalyzed reaction/ biological activity:
  • transports the forespore chromosome across the sporulation septum PubMed
  • translocates septum-entrapped DNA only when septum closure precedes complete segregation of chromosomes PubMed
  • the two DNA translocases SftA and SpoIIIE synergistically affect chromosome dimer resolution presumably by positioning the dif sites in close proximity, before or after completion of cell division, respectively PubMed
  • binds DNA sequences named SRS for SpoIIIE recognition sequence, GAGAAGGG PubMed

• Protein family:

• Paralogous protein(s): SftA
