reduktaasi
Reduktaasi, or reductase, is a broad term for enzymes that catalyze reduction reactions in which substrates gain electrons. In biochemistry, reductases are typically a subset of oxidoreductases (EC class 1) and often use cofactors such as NADPH, NADH, FAD, or FMN to donate electrons. They play key roles in metabolism, biosynthesis, and detoxification by converting carbonyl compounds, nitro groups, or unsaturated bonds into more reduced forms.
Common reductase families include aldo-keto reductases (AKRs), which reduce carbonyl groups to corresponding alcohols, and the
Cofactor dependence varies among reductases. The majority use NADPH as a primary electron donor in anabolic
Biological and practical significance is broad. In humans, reductases participate in steroid metabolism, xenobiotic detoxification, and
