Medium-Chain-Length Fatty Acid Catabolism in Cupriavidus necator H16: Transcriptome Sequencing Reveals Differences from Long-Chain-Length Fatty Acid β-Oxidation and Involvement of Several Homologous Genes.

ABSTRACT: The number of genes encoding β-oxidation enzymes in Cupriavidus necator H16 (synonym, Ralstonia eutropha H16) is high, but only the operons A0459-A0464 and A1526-A1531, each encoding four genes for β-oxidation enzymes, were expressed during growth with long-chain-length fatty acids (LCFAs). However, we observed that C. necator ΔA0459-A0464 ΔA1526-A1531 and C. necator H16 showed the same growth behavior during growth with decanoic acid and shorter FAs. The negative effect of the deletion of these two operons increased with an increasing chain length of the utilized FAs. Transcriptome sequencing (RNA-Seq) revealed the expression profiles of genes involved in the catabolism of medium-chain-length fatty acids (MCFAs) in C. necator H16. Operon A0459-A0464 was expressed only during growth with n
