Superoxide dismutase (EC 1.15.1.1;SOD) is a metal-containing enzyme that widely exist in organisms. It catalyzes the dismutation of superoxide free radical and produces hydrogen peroxide and oxygen.It plays an important role in protecting the plasmalemma from the reactive oxygen species.A recombinant plasmid pPICZA-sodM18 was constructed and after its linearization was transferred into chromosome of Pichia pastoris GS115 by electroporation.

超氧化物歧化酶(Superoxide dismutase；EC 1.15.1.1；SOD)是广泛存在于生物体内的金属酶，是机体内唯一以超氧阴离子自由基(O_2~-)为底物的酶，它能专一地催化O_2~-的歧化反应，生成过氧化氢和氧气，能有效的抵御氧自由基和其他氧化物自由基对细胞质膜的毒性，对机体防御氧化损伤起着十分重要的作用。
