1.1.1.53 | 11-deoxycortisol + NADH + H+ |
i.e. 4-pregnen-17,21-diol-3,20-dione, 49.8% of the activity compared to cortisone |

1.1.1.53 | 20beta-hydroxycortisone + NADH + H+ |
under in vitro conditions, the enzyme catalyzes reductive reaction far more readily than oxidative reaction |

1.1.1.53 | cortisone + NADH + H+ |
the equilibrium for the recombinant enzyme clearly favors the reductive direction. Cortisol is the preferred substrate, as it is more rapidly converted to 20beta-dihydrocortisol relative to other structurally similar steroids tested |
