摘要

摘要: 碳酸酐酶CA(EC 4.2.1.1)是含锌原子的金属蛋白酶,该酶的基本功能是催化CO₂与HCO₃^-间的相互转换^[1].该反应在许多生物过程中都发挥着重要的作用,例如离子交换、呼吸作用、pH稳定性、捕获CO₂和光合作用等^[2~5].CA广泛分布于各种生物中,已知的CA酶根据氨基酸序列被分为-αCA,-βCA和γ-CA三种类型^[5~7].这3种类型的CA酶序列间的相似性很低,被认为是由不同的途径进化而来的^[7].α-型的CA酶在动物、植物、绿藻、细菌和蓝细菌中都有发现^[7],在藻类中报道的α-型CA还很少.迄今为止只在衣藻中发现2种异构体,在盐藻中发现3种^[8,9],在红藻中还未见报道.
