Induction of alkane hydroxylase proteins by unoxidized alkane in Pseudomonas putida.
In vitro complementation assays have been used to demonstrate the induction of alkane hydroxylase proteins in mutants lacking the ability to convert n-alkanes to their primary alcohols. Purified heptane is an effective inducer in a mutant lacking detectable hydroxylase activity.
متن کاملFractionation of inducible alkane hydroxylase activity in Pseudomonas putida and characterization of hydroxylase-negative plasmid mutations.
The plasmid-determined inducible alkane hydroxylase of Pseudomonas putida resolved into particulate and soluble fractions. Spinach reductase and spinach ferredoxin could replace the soluble hydroxylase component. Two alkane hydroxylase mutants show in vitro complementation (S. Benson and J. Shapiro, J. Bacteriol., 123: 759-760, 1975): one, alk-7, lacks an active soluble component and the other,...
متن کاملCharacterization and two-dimensional crystallization of membrane component AlkB of the medium-chain alkane hydroxylase system from Pseudomonas putida GPo1.
The alkane hydroxylase system of Pseudomonas putida GPo1 allows it to use alkanes as the sole source of carbon and energy. Bacterial alkane hydroxylases have tremendous potential as biocatalysts for the stereo- and regioselective transformation of a wide range of chemically inert unreactive alkanes into valuable reactive chemical precursors. We have produced and characterized the first 2-dimens...
متن کاملRole of the crc gene in catabolic repression of the Pseudomonas putida GPo1 alkane degradation pathway.
Expression of the alkane degradation pathway encoded in the OCT plasmid of Pseudomonas putida GPo1 is induced in the presence of alkanes by the AlkS regulator, and it is down-regulated by catabolic repression. The catabolic repression effect reduces the expression of the two AlkS-activated promoters of the pathway, named PalkB and PalkS2. The P. putida Crc protein participates in catabolic repr...
متن کاملPlasmid-determined alcohol dehydrogenase activity in alkane-utilizing strains of Pseudomonas putida.
We have identified an alcohol dehydrogenase activity in Pseudomonas putida strains carrying the CAM-OCT degradative plasmid that were grown on octane. The activity is nicotinamide adenine dinucleotide independent, sediments at 48,000 x g, and shows 20-fold greater activity with octanol rather than butanol as substrate. The enzyme is inducible by unoxidized alkane and is present only in strains ...
