RecF protein-SOS mediator protein
The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. When DNA is damaged and forms single-stranded DNA, Rec A binds single-stranded DNA (ssDNA). The binding of RecA onto ssDNA forms a nucleoprotein filament that promotes LexA cleavage (thereby inducing the SOS response). Recombinase mediator proteins RecF, RecO, and RecR act together to promote loading of RecA onto single stranded DNA.
Background
RecA is a protein in nearly all bacteria and all organisms. Following a break on a single-stranded DNA (ssDNA), the exonuclease RecJ cleaves single-stranded DNA. The single-strand DNA-binding protein (SSB) binds to the daughter strand gap, preserving the integrity of the DNA. Recombinase mediator proteins RecF, RecO, and RecR act together to promote loading of RecA onto single stranded DNA. Rec A binds single-stranded DNA (ssDNA), forming a nucleoprotein filament that promotes LexA cleavage (thereby inducing the SOS response).
