Partial purification and characterisation of Bfi57I and Bfi89I, restriction endonucleases from different strains of Butyrivibrio fibrisolvens.
Two class-II restriction endonucleases (ENases), Bfi57I and Bfi89I, were partially purified from Butyrivibrio fibrisolvens OB157 and OB189, respectively. Bfi57I (isoschizomer Sau3AI) had the DNA recognition/cleavage sequence 5'-/GATC-3'; it is not inhibited by Dam methylation, but is partially inhibited by M.BamHI methylation. Bfi89I (isoschizomer EaeI) had the recognition/cleavage sequence 5'-Y/GGCCR-3'; unlike the EaeI isoschizomer it is not fully inhibited by M.HaeIII methylation.
