| + | [https://www.uniprot.org/uniprot/KSHA_MYCTU KSHA_MYCTU] Catalyzes the opening of ring B of 1,4-androstadiene-3,17,-dione (ADD) and 4-androstene-3,17-dione (ADD) with concomitant aromatization of ring A. The ring B is subsequently hydroxylated to yield a catechol and then subject to meta-cleavage. | ||
