Introduction
RecA protein participates in general recombination, repair of DNA. It has been observed in vitro to have DNA-dependent ATPase activity, promote proteolytic cleavage of repressors and to catalyze DNA strand pairing and exchange. In the presence of ATP, RecA Protein promotes the strand exchange of single-strand DNA fragments with homologous duplex DNA.
Description
The RecA protein binds strongly and in long clusters to ssDNA to form a nucleoprotein filament. The protein has more than one DNA binding site, and thus can hold a single strand and double strand together. This feature makes it possible to catalyze a DNA synapsis reaction between a DNA double helix and a complementary region of single stranded DNA.
