Abstract
Cytochrome P450 enzymes (CYP enzymes) catalyze important metabolic reactions of exogenous and endogenous substrates, including fatty acid. In this study, we cloned the complete CDS of the cytochrome P450 2AA (CYP2AA) gene from the grass carp (Ctenopharyngodon idella) for the first time. CYP2AA consisted of 1500 bp, which encoded a predicted protein of 499 amino acids. The identities of CYP2AA between C. idella and zebrafish were 86%. It consists of the conserved heme-binding motif FXXGXXXCXG. Quantitative real-time PCR analysis indicated that CYP2AA mRNA in C. idella was highly expressed in liver and adipose tissue. The effects of fish oil and lard oil in diets on expression of CYP2AA mRNA in vivo were also investigated. The fish oil (FO) group exhibited significantly higher CYP2AA expression in adipose tissue than the lard oil (LO) group (P < 0.01), whereas the mRNA expression of CYP2AA was not notably different in liver. It suggested that the high abundance of CYP2AA mRNA expression in adipose tissue could be induced by fish oil. Our findings provided molecular characterization and expression profile of CYP2AA, and enhanced our understanding of CYP2AA in fish lipid metabolism.
