Characterization and engineering of a novel pyrroloquinoline quinone dependent glucose dehydrogenase from Sorangium cellulosum So ce56.
本研究从Sorangium cellulosum So ce56中分离获得一种新型吡咯喹啉醌（PQQ）依赖葡萄糖脱氢酶样酶，克隆其推测编码区并在大肠杆菌中过表达，对重组酶进行纯化与表征。重组蛋白表观相对分子质量为63 kDa，与Acinetobacter calcoaceticus的PQQ GDH-B具有43%同源性。在PQQ和Ca...
