Abstract (l-)5,10-Methenyltetrahydropteroyltriglutamic acid was isolated from Clostridium acidi-urici. The procedure yielded approximately 25 mg of this stable derivative of the natural folate coenzyme per 100 g of wet cells. (l)-Tetrahydropteroyltriglutamate was synthesized by enzymic arsenolysis of the product. Procedures for the synthesis of (l)-10-[14C]formyltetrahydropteroyltriglutamate, (l)-10-formyl-[6,7-3H2]tetrahydropteroyltriglutamate, and (l)-[6,7-3H2]tetrahydropteroyltriglutamate with a high specific radioactivity are described.
