Cre recombinase. Cre recombinase is a tyrosine recombinase enzyme derived from the P1 Bacteriophage. The enzyme uses a topoisomerase I like mechanism to carry out site specific recombination events. The enzyme is a member of the integrase family of site specific recombinase and it is known to catalyse the site specific recombination event between two DNA recognition sites. This 34 base pair loxP recognition site consists of two 13 bp palindromic sequences which flank an 8bp spacer region. The products of Cre-med
