Resumo
From the Bacillus species D6 strain, the restriction endonuclease BspD6II has been isolated and characterized. It recognizes the asymmetric region 5′-CTGAAG-3′/3′-GACTTC-5′ in the double-stranded DNA. The sites of DNA hydrolysis by this enzyme have been determined. They are localized beyond the recognition site 16 nt downstream of the sequence 5′-CTGAAG-3′ toward the 3′-end of DNA and 14 nt toward the 5′-end in the opposite strand. It has been shown that BspD6II differs in properties from isoschizomer enzymes Eco57I (prototype), AcuI, and BspKT5I and has some advantages. It catalyzes the exhaustive hydrolysis of DNA in the absence of S-adenosyl-L-methionine and effectively operates at 50°C, i.e., is a thermophilic enzyme.
