Tma endoV M2-6 is an endonuclease having modified substrate specificity created by amino acid substitutions to Tma endoV (endonuclease V from thermophilic bacterium Thermotoga maritima). TmaendoV has a deoxyinosine 3'-endonuclease activity, i.e. it recognizes a hypoxanthine (the deoxyinosine base) and exhibits a nicking activity to hydrolyze the second phosphodiester bond to 3' the lesion base(1-4). The wild-type endoV also shows nonspecific DNA cleaving activities, independent of the specific recognition of the lesion structure. Tma endoV M2-6 exhibits a significantly reduced nonspecific activity toward an intact DNA and retains the specific endonuclease activity against a deoxyinosine-containing DNA.
Endonucelase V
Purified from Escherichia coli cells carrying a mutant endonuclease V gene (nfi gene), which was cloned from Thermotoga maritima and introduced site-directed mutagenesis
[NOTE] This product cannot be sold to USA because of the patent issue.
