The bacterial recA protein [1,2,3] is essential for homologous recombination and recombinational repair of DNA damage. RecA has many activities: it filaments, it binds to single- and double-stranded DNA, it binds and hydrolyzes ATP, it is also a recombinase and, finally, it interacts with lexA causing its activation and leading to its autocatalytic cleavage.
The recA protein is closely related to:
As a signature pattern specific for the bacterial and chloroplastic recA protein, we selected the best conserved region, a nonapeptide located in the middle of the sequence and which is part of the monomer-monomer interface in a recA filament.
We also developed two profiles. The first one covers the ATP binding domain in the N-terminal part of the recA protein. The second one span the whole monomer-monomer interface. These two profiles also pick up the recA-like proteins.
