This domain is found in a group of GMC oxidoreductases mainly from actinomycetes, including Cholesterol oxidase from Streptomyces sp. (ChoA). ChoA is organised into two domains, an FAD-binding domain (Pfam:PF00732) and a substrate binding domain (formed by this entry and Pfam:PF05199) [1-5]. This domain consists of six beta -sheets and one alpha-helix.	Domain
