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

(rĭ-dŭk′tās′, -tāz′)
n.
Any of various enzymes that catalyze the reduction of an organic compound.

reductase

A generic term for any enzyme that catalyses a chemical reduction reaction.

re·duc·tase

(rĕ-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.
