BmtI-HF® is produced in E. coli from a strain that carries the cloned BmtI gene from Bacillus megaterium S2 (S.K. Degtyarev).

High Fidelity (HF®) Restriction Enzymes have 100% activity in CutSmart® Buffer; single-buffer simplicity means more straightforward and streamlined sample processing. HF enzymes also exhibit dramatically reduced star activity. HF enzymes are all Time-Saver™ qualified and can therefore cut substrate DNA in 5-15 with the flexibility to digest overnight without degradation to DNA. Engineered with performance in mind, HF restriction enzymes are fully active under a broader range of conditions, minimizing off-target products, while offering flexibility in experimental design.
