A key component of Dr. Banta’s work is engineering AdhD to accept a broad range of substrates. This is a crucial component of his work, because this enzyme will be required to act upon a wide range of substrates when it is used within a practical biofuel cell. Rat liver 3-alpha-hydroxysteroid dihydrodiol dehydrogenase demonstrates how an enzyme is specific to certain substrates and therefore help show what might be done to broaden the specificity of an enzyme. The function of this enzyme within the rat liver is to regulate / activate / deactivate steroid hormones. The enzyme does this is by reducing or oxidizing the steroid’s (testosterone) C3 ketone group. The interactions within the active site and testosterone are very specific because of the structure and positioning of the residues within the cavity. This information is important, because it will help show what might be done to AdhD to broaden its substrate specificity. | A key component of Dr. Banta’s work is engineering AdhD to accept a broad range of substrates.
