[Regulation of the expression of plasmid determination responsible for caprolactam degradation by bacteria of the genus Pseudomonas].
On the basis of the study of some Tn5 induced mutants in Pseudomonas putida strain BS836 containing the plasmid pBS268 coding caprolactam degradation, growth on caprolactam and its intermediates, and the data on the induction of oxidative activities in plasmid containing P. putida strain BS831 it was shown that plasmid and chromosome genes regulated the expression of CAP-determinants. The regulation has some elements of the negative control mechanism. Caprolactam is the inducer of the synthesis of key enzymes cleaving it and its intermediates (aminocaproic and adipic acids). At the same time each of its intermediates induced the synthesis of enzymes responsible for its cleavage.
