title: [Comparative analysis of the organization of the NPL-1 plasmid controlling naphthalene oxidation in Pseudomonas putida and its derivatives].
abstract: The paper contains the data on the structure of NPL-1 plasmid controlling naphthalene biodegradation. The plasmid which pertains to the P-9 incompatibility group is transferrable conjugatively and is maintained stably within a wide range of gram-negative bacteria. The analysis of mutants and transposon derivatives of the plasmid made it possible to localize nah-genes in a DNA fragment, 23 kb in size. An inverted DNA segment of 4.2 kb was discovered which may participate in the regulation of nah-genes expression. The other peculiar features of NPL-1 were found distinguishing it from NAH and NAH7 plasmids described in literature.
