Aromatase. Androstenedione Aromatase . CYP 19 . CYP19 Protein . Cytochrome P450 19 . Estrogen Synthase . Estrogen Synthetase . P450AROM . Aromatase, Androstenedione . Cytochrome P 450 CYP19 . Protein, CYP19 . Cytochrome P-450(AROM) . Cytochrome P-450 CYP19 . CYP19 . An enzyme that catalyzes the desaturation (aromatization) of the ring A of C19 androgens and converts them to C18 estrogens. In this process, the 19-methyl is removed. This enzyme is membrane-bound, located in the endoplasmic reticulum of estrogen-producing cells of ovaries, placenta, testes, adipose, and brain tissues. Aromatase is encoded by the CYP19 gene, and functions in complex with NADPH-FERRIHEMOPROTEIN REDUCTASE in the cytochrome P-450 system. . 0.34
