Nucleolytic activities in<i>Lactococcus lactis</i>subsp.<i>lactis</i>NCDO 497

Abstract

Two nucleolytic activities were detected in Lactococcus lactis subsp. lactis NCDO 497. One of them was a specific endonuclease, located in the cytoplasm, with the typical characteristics of type II restriction endonucleases. The second activity was a non-specific deoxyribonuclease with exocytoplasmic location.
