Abstract
A 74 kD protein was extracted from Escherichia coli cells and purified under the physiological conditions. The protein is able to catalyze the reactions of endonucleolytic degradation of plasmid DNA. The genetic determinant coding for the 74 KD protein synthesis has been localized between 17 and 27 min on Escherichia coli chromosomal map. The endonuclease previously described as a recF gene dependent "protein Z" (Krivonogov S. V., Novitskaja V. A. Mol. Gen. Genet., 1982, v, 187, p. 302) is shown to be independent of the integrity of Escherichia coli recF gene.
