Oligo(cis-1,4-isoprene) aldehyde-oxidizing dehydrogenases of the rubber-degrading bacterium Gordonia polyisoprenivorans VH2

Abstract: The actinomycete Gordonia polyisoprenivorans strain VH2 is well-known for its ability to efficiently degrade and catabolize natural rubber [poly(cis-1,4-isoprene)]. Recently, a pathway for the catabolism of rubber by strain VH2 was postulated based on genomic data and the analysis of mutants (Hiessl et al. in Appl Environ Microbiol 78:2874-2887, 2012). To further elucidate the degradation pathway of poly(cis-1,4-isoprene), 2-dimensional-polyacrylamide gel electrophoresis was performed. The analysis of the iden… Show more

“…The recognition motifs were identified as TGTGCN 6 TCACA, TGTGAN 6 ACACT, TGTGAN 6 TCACA, and TGTGTN 6 ACACG for the aldehyde dehydrogenase, the long-chain fatty acid-CoA ligase, the putative trehalose importer operon, and the ␣-methylacyl-CoA racemase, respectively. Previous studies already discovered a participation of these enzymes in the degradation of poly(cis-1,4-isoprene) (32,38). Hence, we identified additional CRP VH2 regulation targets related to the degradation of the polymer in G. polyisoprenivorans VH2.…”

“…In addition to the ␤-oxidation pathway, CRP VH2 might also be involved in regulating the expression of an operon putatively encoding a trehalose importer. Previous studies discovered an increased abundance of the putative trehalose importer under poly(cis-1,4-isoprene)-degrading conditions (32). As trehalose is linked to mycolic acids, enabling adhesive growth on the polymer, CRP VH2 might also promote adhesive growth of G. polyisoprenivorans VH2 by increasing trehalose recycling (32).…”
