Abstract:
:The DNA of bacteriophage Mu, extracted from induced lysates, is partially resistant to digestion by the endonuclease BalI. This modification of DNA is controlled by the Mu modification function (mom), which acts in conjunction with the dam (DNA-adenine methylation) function of Escherichia coli. Since the BalI recognition site is apparently different from the dam recognition site, these results imply that either the specificity of the dam function is changed by the mom function or the mom function requires the dam function for its activity.
