recA-57E
Species
E. coli
Product Name
Recombinant E.coli RecA
Product Overview
A recombinant E. coli strain overexpressing E. coli recA from a plasmid.
Description
RecA functions in DNA recombination and DNA repair. RecA binds to single stranded DNA, resulting in the polymerization of RecA into a nucleoprotein complex. This complex can align with complementary double stranded DNA, resulting in RecA catalysis of DNA strand exchange. RecA DNA binding is stimulated by ATP hydrolysis or non-hydrolyzable ATP analogs. The RecA-ATP-single stranded DNA complex also can function as a coprotease factor in the proteolytic cleavage of LexA, UmuD and certain bacteriophage proteins. RecA complexed with site-specific oligonucleotides have been used to target and specifically cleave large DNA fragments.
