Summary

Alkane oxidation functions encoded by the Pseudomonas plasmid CAM-OCT are positively regulated by one or more products of a locus designated alkR. To characterize this locus in greater detail, molecular cloning and restriction mapping of sequences covering the alkR region have been carried out in Escherichia coli, followed by mobilization to Pseudomonas recipients for analysis of genetic content. Inserts from Pseudomonas (CAM-OCT) strains were cloned into vectors pLAFR1, the pLAFR1::Tn7S derivative pXJS5403, and the transposon vector Tn3Δ596. This has made it possible to: (1) construct a detailed restriction map of cloned fragments and the alkR region of CAM-OCT; (2) map insertion sites of the transposon Tn7S into alkR cistrons; and (3) analyze the ability of cloned sequences to complement or effect marker rescue of alkR nitrosoguanidine- and Tn7S-induced mutations. In addition, transcription of an alkB'-lacZ transcription fusion in the presence of a cloned 18.5 kb EcolRI alkR fragment and an inducer of the alk system confirmed that our cloned sequences contain functional alkR cistrons. The complementation/marker rescue results indicate that alkR is a complex locus and that the products of at least three cistrons are required for the complete AlkR+ phenotype. One of these cistrons is identified by mutations which alter a component of the inducer recognition system.
