Yeast surface displaying glucose oxidase as whole-cell biocatalyst: construction, characterization, and its electrochemical glucose sensing application.
本研究成功利用α-凝集素作为锚定基序,将葡萄糖氧化酶(GOx)展示于酿酒酵母细胞表面。免疫化学分析与酶学分析表明,具有活性的GOx被高效表达并转运至细胞表面。与传统GOx相比,展示GOx的酵母细胞(GOx-yeast)表现出优良的酶学性质:在宽pH范围(pH 3.5–11.5)内稳定性良好,热稳定性高(52 °C下保留超过94.8%...
