title: Studies on a membrane-bound and solubilized ribonucleotide reductase preparation from Escherichia coli TAU-.
abstract: Ribonucleotide reductase has been shown to be associated with the DNA-membrane complex in Escherichia coli TAU- cells. The membrane-bound enzyme has been released in a soluble form using a combined treatment of 1% sarcosyl (pH 8.0) and 1% sodium deoxycholate (pH 6.5). Allotropic differences in the modulatory effects of ATP, Mg2+, EDTA and dithiothreitol on the membrane-bound and solubilized enzyme activity are discussed.
