  • Title: Functional characterization of genes involved in alkane oxidation by Pseudomonas aeruginosa.
    Author: Smits TH, Witholt B, van Beilen JB.
    Journal: Antonie Van Leeuwenhoek; 2003; 84(3):193-200. PubMed ID: 14574114.
    Abstract:
    Most clinical isolates identified as Pseudomonas aeruginosa grow on long-chain n-alkanes, while environmental P. aeruginosa isolates often grow on medium- as well as long-chain n-alkanes. Heterologous expression showed that the two alkane hydroxylase homologs of P. aeruginosa PAO1 (AlkB1 and AlkB2) oxidize C(12)-C(16)n-alkanes, while two rubredoxin (RubA1 and RubA2) and a rubredoxin reductase (RubB) homologs can replace their P. putida GPo1 counterparts in n-octane oxidation. The two long-chain alkane hydroxylase genes are present in all environmental and clinical isolates of P. aeruginosa strains tested in this study.
