Accession ID Name Pfam Type
PF18897 Recombination directionality factor-like family

This entry includes Gp3 from Streptomyces phage phiC31. Gp3 is a recombination directionality factor that interacts directly with the integrase tetramer to activate excision and inhibit integration [1]. The characteristics of the protein distribution suggest prophage matches in addition to the phage matches.
