酪氨酸羟化酶

酪氨酸羟化酶(英語:Tyrosine hydroxylase)或酪氨酸3-单加氧酶(英語:tyrosine 3-monooxygenase)是负责催化氨基酸L-酪氨酸转变为二羟基苯丙氨酸(多巴)的[1][2]。因此它使用四氢生物蝶呤作为辅酶。多巴是多巴胺的一个前体,相应地,后者亦是去甲肾上腺素肾上腺素的前体。在人体中,酪氨酸羟化酶由TH基因编码出来[2]

反应

加氧酶被发现与所有含儿茶酚胺的细胞溶质中。此起始步骤是产生儿茶酚胺的限速步骤

此酶有高度地特异性,不会接受吲哚的衍生物——这一点确实与许多其他涉及到产生儿茶酚胺的酶迥异的地方。

 
酪氨酸羟化酶催化酪氨酸生成二羟基苯丙氨酸

临床意义

酪氨酸羟化酶可以被药物α-甲基-对-酪氨酸(甲基酪氨酸)所抑制。此抑制作用可以导致脑部多巴胺与去甲肾上腺素的消耗,这是因为缺乏前体L-多巴(L-3,4-二羟基苯丙氨酸),此物质可以由酪氨酸羟化酶所合成。此药很少被使用并会导致抑郁,但它在治疗嗜铬细胞瘤以及抗高血压方面很有用处。

在自體免疫性多内分泌腺病综合征(APS)I型中,酪氨酸羟化酶是一个自身抗原[3]

在文献中提到的抑制剂的老例子是奥德么酮[4]与水绫霉素[5]
