WebConclusions: TspDTI, TsoI and isoschizomers Tth111II/TthHB27I are closely related bifunctional enzymes. They comprise a tandem arrangement of Type I-like domains, like other Type IIC enzymes (those with a fusion of a REase and MTase domains), e.g. TspGWI, TaqII and MmeI, but their sequences are only remotely similar to these WebTth111II is a thermostable Type IIGS restriction enzyme that recognizes DNA sites CAARCA (R 5 A or G) and cleaves downstream at N11/N9. Here, the tth111IIRM gene was cloned and expressed in E. coli, and Tth111II was purified. The purified enzyme contains internally-bound S-adenosylmethionine (SAM).

WebTth111II is a thermostable Type IIGS restriction enzyme that recognizes DNA sites CAARCA (R = A or G) and cleaves downstream at N11/N9. Here, the tth111IIRM gene was cloned … WebAug 11, 1980 · A second site specific endonuclease with novel specificity has been purified from Thermus thermophilus strain 111 and named Tth111II. The enzyme is active at temperature up to 80 degrees C and requires Mg2+ or Mn2+ for endonuclease activity. Tth111II cleaves phi X174RFDNA into 11 fragments and lambda NA into more than 25 … WebAug 6, 2013 · Background In continuing our research into the new family of bifunctional restriction endonucleases (REases), we describe the cloning of the tsoIRM gene. Currently, the family includes six thermostable enzymes: TaqII, Tth111II, TthHB27I, TspGWI, TspDTI, TsoI, isolated from various Thermus sp. and two thermolabile enzymes: RpaI and CchII, … scambs statement of accounts
