Abstract excerpt
The present work describes mutants of the restriction enzyme EcoRV that discriminate very efficiently between oligodeoxynucleotide substrates with an EcoRV recognition sequence in different sequence context. All of these EcoRV variants harbor substitutions at position 226, where in the cocrystal structure of the specific EcoRV/DNA complex an arginine contacts the backbone of the DNA substrate upstream of the...
