title: Isolation and characterization of the StyD4I restriction endonuclease, a neoschizomer of ScrFI, from Escherichia coli K-12 carrying a small multicopy Hsd plasmid of Salmonella typhi origin.
abstract: A restriction endonuclease, designated StyD4I, a neoschizomer of ScrFI, has been isolated from Escherichia coli K-12 carrying a small multicopy host specificity for DNA (Hsd) plasmid of Salmonella typhi D4 origin. In the presence of 10 mM Mg2+, StyD4I cleaves the sequence 5'-/CCNGG-3' and generates a 5-nucleotide cohesive end. StyD4I should be useful for recombinant DNA technology, because of the stability and ease in handling the producer cells.
