ABSTRACT
Abstract NADPH-cytochromeP450 reductase (CPR) is one of the most important components of the cytochrome P450 enzyme system. In this study, a gene encoding CPR (named EsCPR) was isolated from Eriocheir sinensis using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) methods. Analysis of the nucleotide sequence revealed a cDNA full-length of 3717 bp with an open reading frame of 2046 bp, a 5′-untranslated region of 42 bp, and a long 3′-untryganslated region of 1628bp, which encodes a protein of 681 amino acids with a predicted molecular weight of 30.7 kDa and an estimated pI of 4.82. The mature peptide shares amino acid of E. sinensis identity 82 % - 89 % to the CPR from Penaeus vannamei and Chionoecetes opilio. Tissues and developmental stage-dependent expression of EsCPR mRNA was investigated by real-time quantitative PCR. EsCPR mRNA was markedly expressed in the hepatopancreas and stomach. These results would provide valuable information for further study on the interactions between CPR and cytochrome P450 enzyme systems.
