Homogenates of gill plates of Mytilus edulis L. used oxygen when 5-hydroxytryptamine was added. The oxidation of 5-hydroxytryptamine was not due to the presence of an amine oxidase, but to that of an enzyme that catalysed the oxidation of other 5-hydroxyindoles (5-hydroxytryptophan, bufotenine). The oxidation was cyanide-sensitive, but was not inhibited by iproniazid. In the reaction a yellowish-brown substance was formed. The occurrence of an amine oxidase in the anterior retractor muscle of the byssus and in the digestive gland was confirmed.
添加5-羟色胺时,紫贻贝鳃板匀浆会消耗氧气。5-羟色胺的氧化并非由于胺氧化酶的存在,而是由于一种能催化其他5-羟吲哚(5-羟色氨酸、蟾蜍色胺)氧化的酶。该氧化反应对氰化物敏感,但不受异烟肼抑制。反应中会形成一种黄褐色物质。证实了足丝前牵缩肌和消化腺中存在胺氧化酶。
