Enzyme Commission Number
EC 1.3.1.22
Product Overview
High-quality enzyme products.
Well-established quality management system.
Reaction
a 3-oxo-5α-steroid + NADP+ = a 3-oxo-Δ4-steroid + NADPH + H+
Systematic Name
3-oxo-5α-steroid:NADP+ Δ4-oxidoreductase
Function
The enzyme catalyses the conversion of assorted 3-oxo-Δ4 steroids into their corresponding 5α form. Substrates for the mammalian enzyme include testosterone, progesterone, and corticosterone. Substrates for the plant enzyme are brassinosteroids such as campest-4-en-3-one and (22α)-hydroxy-campest-4-en-3-one. cf. EC 1.3.99.5, 3-oxo-5α-steroid 4-dehydrogenase (acceptor).
