Mutants of the EcoRI endonuclease with promiscuous substrate specificity implicate residues involved in substrate recognition.

The EcoRI restriction endonuclease cleaves DNA molecules at the sequence GAATTC. We devised a genetic screen to isolate EcoRI mutants with altered or broadened substrate specificity. In vitro, the purified mutant enzymes cleave both the wild-type substrate and sites which differ from this by one nuc...
