title: Recombination at ColE1 cer requires the Escherichia coli xerC gene product, a member of the lambda integrase family of site-specific recombinases.
abstract: Site-specific recombination at the plasmid ColE1 cer site requires the Escherichia coli chromosomal gene xerC. The xerC gene has been localized to the 85-min region of the E. coli chromosome, between cya and uvrD. The nucleotide sequences of the xerC gene and flanking regions have been determined. The xerC gene encodes a protein with a calculated molecular mass of 33.8 kDa. This protein has substantial sequence similarity to the lambda integrase family of site-specific recombinases and is probably the cer recombinase. The xerC gene is expressed as part of a multicistronic unit that includes the dapF gene and two other open reading frames.
