What is T7 Endonuclease I?

T7 Endonuclease I (T7EI / T7E1) is a homodimeric enzyme composed of 149-amino-acid subunits derived from T7 phage. In addition to resolving four-way Holliday junctions—crucial intermediates formed during both homologous recombination and site-specific recombination—T7EI exhibits cleavage activity against a variety of mismatched DNA structures, ranging from branched DNA to heteroduplexes with base mismatches. This characteristic allows for the detection of DNA mutations based on the presence or absence of DNA cleavage.
