FIELD: microbiology, biotechnology, genetic engineering. SUBSTANCE: new strain of Bacillus coagulans (ВКПМ B-6670) is proposed as a producer of restriction endonuclease Bco631 I. Strain is isolated from thermal sources as a result of screening. Enzyme yield is 6000 U/g wet biomass, specific activity of the end enzyme is 10000 U/ml. Restrictase Bco631 I is an isoschizomer of restrictase Bsa BI and can replace the latter in all genetic engineering investigations. EFFECT: new strain of bacterium indicated above, high yield of the end enzyme. 1 dwg
