Accessory recombination function protein (IPR020293)

Short name: Arf

Family relationships



The accessory recombination function (arf) gene of bacteriophage P22 is located immediately upstream of the essential recombination function (erf) gene. Mutants of arf are partially defective in homologous recombination and plaque formation in wild-type and recA hosts; their defects are more severe in recB and recA recB hosts. Recombinant plasmids expressing arf complement the growth defect of arf- phages. The plasmids also stimulate erf-mediated recombination and cause a stimulation of recA-recBCD-mediated homologous recombination of phage lambda [PMID: 1827223].
