Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • activation of gene expression at the onset of sporulation (Spo0A regulon)
    • coordination between DNA replication and initiation of sporulation by binding to sites close to the oriC (this limits re-initiation of replication) PubMed
