Abstract This review summarises current information on the site-specific recombinases encoded by the plasmids of the Gram-positive bacteria that have low guanine and cytosine content in their DNA. It focuses on the peculiar biological features of the recombination systems encoded by the theta-replicating plasmids and compares them with the site-specific recombinases encoded by transposons or plasmids originally isolated from Gram-negative bacteria.
