- Aromatase is encoded by the CYP19 gene, and functions in complex with NADPH-FERRIHEMOPROTEIN REDUCTASE in the cytochrome P-450 system. (uams.edu)
NADH or NADPH3
- This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with a heme protein as acceptor. (wikipedia.org)
- A group of oxidoreductases that act on NADH or NADPH. (lookformedical.com)
- In general, enzymes using NADH or NADPH to reduce a substrate are classified according to the reverse reaction, in which NAD+ or NADP+ is formally regarded as an acceptor. (lookformedical.com)
Enzyme that catalyzes1
- In enzymology, a NADPH-hemoprotein reductase is an enzyme that catalyzes the chemical reaction NADPH + H+ + n oxidized hemoprotein ⇌ {\displaystyle \rightleftharpoons } NADP+ + n reduced hemoprotein The 3 substrates of this enzyme are NADPH, H+, and oxidized hemoprotein, whereas its two products are NADP+ and reduced hemoprotein.

Systematic name2
- The systematic name of this enzyme class is NADPH:hemoprotein oxidoreductase. (wikipedia.org)
- The systematic name is based on donor:acceptor oxidoreductase. (lookformedical.com)
