Abstract: | The enzyme system for the synthesis of the pteridine pigment, sepiapterin, from triphosphate (dihydroneopterin triphosphate) has been found in extracts of . NADP+ or NADPH and Mg2+ are required for this enzymatic transformation. No sepiapterin is produced when dihydroneopterin is supplied as substrate in place of dihydroneopterin triphosphate. |
