the enzyme performs regioselective oxidation of indole- and quinolinecarboxylic acids, it oxidizes 2-naphthoic acid and 4-ethylbenzoic acid, substrate specificity and regioselectivity of CYP199A2, overview. CYP199A2 does not exhibit any activity towards indole and indole-3-carboxylic acid, whereas this enzyme oxidizes indole-2-carboxylic acid, indole-5-carboxylic acid, and indole-6-carboxylic acid. Indole-2-carboxylic acid is converted to 5- and 6-hydroxyindole-2-carboxylic acids at a ratio of 59:41. In contrast, the indole-6-carboxylic acid oxidation generates only one product, 2-indolinone-6-carboxylic acid. The oxidation product of quinoline-6-carboxylic acid is 3-hydroxyquinoline-6-carboxylic acid
