金属蛋白(英語:Metalloprotein)是一类含有配位结合的金属离子作为辅因子的结合蛋白质[1][2]。所有蛋白质中有大量是属于这一类。
这是一类非常重要的蛋白质,在细胞中有多种不同的功能,包括作为酶、运输蛋白、贮存蛋白和信号转导蛋白等。其中的金属离子一般是与多肽链上氨基酸残基中的氮、氧或硫原子或与蛋白质相结合的大环配体相配位。由于金属离子的特殊氧化还原性质,金属酶常用作催化生氧化还原反应的催化剂。
功能
据估计,所有蛋白质中有大约一半含有金属[3]。据另一个估计,大约四分之一到三分之一的所有蛋白质被提议要求有金属执行其功能[4]。因此,金属蛋白在细胞中具有许多不同的功能,例如蛋白质的储存和运输,酶和信号转导蛋白。金属离子在感染性疾病中的作用已经被审查[5]。
