[Localization of Kpnl restriction sites in the r-determinant of plasmid NR1].

Restriction KpnI sites on a molecule of the plasmid NR1 were localized. The position of KpnA (58,0 MD) and KpnB (1,0 MD) fragments on a physical map of the NR1 molecule was shown using endonucleases EcoRI and SaII. Both restriction sites are situated on a r-determinant of the EcoJ fragment of the plasmid NR1.
