Lack of regulation of the modification-dependent restriction enzyme McrBC in Escherichia coli.

Mark Murphy1, Stefanie Schmid Nuoffer, Thomas A Bickle.   

Abstract

Restriction alleviation (RA) by the type I restriction enzyme EcoKI is caused by treatments that damage DNA. RA is due to proteolysis of the EcoKI HsdR subunit by the ClpXP ATP-dependent protease. Here we show that the modification-dependent enzyme McrBC is not subject to RA, although it is moderately sensitive to ClpAP.
