Aromatase distribution and regulation in fish
Fish Physiology and Biochemistry, 2005 Cytochrome P450 aromatase is the enzyme complex responsible for the synthesis of estrogens by the aromatization of androgens. In the vast majority of tetrapods examined so far, aromatase is the product of the Cyp19 gene, which exists as a single copy per haploid genome.
