reductase

 [re-duk´tās]
an enzyme that catalyzes a chemical reduction.
5α-reductase an enzyme that catalyzes the irreversible reduction of testosterone to dihydrotestosterone.

re·duc·tase

(rē-dŭk'tās),
An enzyme that catalyzes a reduction; because all enzymes catalyze reactions in either direction, any reductase can, under the proper conditions, behave as an oxidase and vice versa, hence the term oxidoreductase. For individual reductases, see the specific names.
Synonym(s): reducing enzyme

reductase

/re·duc·tase/ (-tās) a term used in the names of some of the oxidoreductases, usually specifically those catalyzing reactions important solely for reduction of a metabolite.
5α-reductase  an enzyme that catalyzes the irreversible reduction of testosterone to dihydrotestosterone; enzyme deficiency leads to a form of male pseudohermaphroditism.
