Three sequence-specific endonucleases from Escherichia coli RFL47.
The characterization of the new restriction enzyme Eco47III recognizing a hexanucleotide palindromic sequence 5'AGC decreases GCT and cleaving, as indicated by the arrow, is reported. It was isolated from Escherichia coli strain RFL47. Another two specific endonuclease Eco47I (isoschizomer of AvaII) and Eco47II (isoschizomer of AsuI) were also found in this strain. There are two Eco47III recognition sites on lambda DNA at 20997 and 37060 basepairs. The central Eco47III fragment can be replaced by a cloned fragment in lambda vector mutant in tR2 gene; i.e., lambda gt.
