production of value‐added chemicals. We describe the construction of self‐assembling all‐enzyme hydrogels that are comprised of two tetrameric enzymes. The stereoselective dehydrogenase LbADH and the cofactor‐regenerating glucose 1‐dehydrogenase GDH were genetically fused with a SpyTag or SpyCatcher domain, respectively, to generate two complementary homo‐tetrameric building blocks that polymerize under physiological
连续流
生物催化是工业
生物技术的新兴领域,它使用固定在流道中的酶生产增值
化学品。我们描述了由两种四聚酶组成的自组装全酶
水凝胶的构建。将立体选择性脱氢酶LbADH和辅因子再生
葡萄糖1脱氢酶GDH分别与SpyTag或SpyCatcher域进行
基因融合,以生成两个互补的均四聚体构件,这些构件在生理条件下聚合成多孔
水凝胶。安装在微流体反应器中,该凝胶显示出优异的立体选择性,在手性酮的还原中具有接近定量的转化率,并且在工艺和储存条件下具有很高的耐用性。
