  • Cloning and expression of cDNA of human Delta4-3-oxosteroid 5beta-reductase and substrate specificity of the expressed enzyme
    作者:Kazu-Hiro KONDO、Masa-Hiro KAI、Yoshiko SETOGUCHI、Gosta EGGERTSEN、Peter SJOBLOM、Toshiaki SETOGUCHI、Kyu-Ichiro OKUDA、Ingemar BJORKHEM
    DOI:10.1111/j.1432-1033.1994.tb19947.x
    日期:1994.1
    The enzyme Δ4‐3‐oxosteroid 5β‐reductase (3‐oxo‐5β‐steroid: NADP+ oxidoreductase and 4,5β‐dihydrocortisone: NADP+Δ4‐oxidoreductase) catalyzes the reduction of the Δ4 double bond of bile acid intermediates and steroid hormones carrying the Δ4‐3‐one structure in the A/B cis configuration. Human Δ4‐3‐oxosteroid 5β‐reductase cDNA was isolated from a liver cDNA library by cross hybridization with a previously cloned rat cDNA, which was used as a probe [Onishi, Y., Noshiro, M., Shimosato, T. & Okuda, K.‐I. (1991) FEBS Lett. 283, 215–218]. DNA sequence analysis of a hybridization‐positive clone predicted the human Δ4‐3‐oxosteroid 5β‐reductase to contain 326 amino acids. The amino acid sequence of the human Δ4‐3‐oxosteroid 5β‐reductase had 79% overall identity to the rat enzyme sequence. It also showed 54% and 50% overall identity with rat 3α‐hydroxysteroid dehydrogenase and human aldose reductase, respectively. RNA blotting analysis demonstrated the existence of a single Δ4‐3‐oxosteroid 5β‐reductase mRNA of approximately 2.7 kb in human liver. Transfection of the cDNA into COS cells resulted in the expression of an active enzyme with a high activity toward the bile acid intermediates 7α,12α‐dihydroxy‐4‐cholesten‐3‐one and 7α‐hydroxy‐4‐cholesten‐3‐one. In addition, the expressed enzyme showed a small but significant 5β‐reduction activity toward 11β,17α,21‐trihydroxy‐Δ4‐pregnene‐3,20‐dione (cortisol) and 17β‐hydroxy‐Δ4‐androsten‐3‐one (testosterone) whereas no activity was observed toward Δ4‐pregnene‐3,20‐dione (progesterone) or Δ4‐androstene‐3‐17‐dione (androstenedione). The substrate specificity of the human enzyme is considerably narrower than that of the rat enzyme, and the enzyme seems to be more important for bile acid biosynthesis than for metabolism of steroid hormones.
