AlphaFold助力设计耐热酶，培育气候适应作物

AI 摘要

密歇根州立大学研究人员利用谷歌DeepMind的AlphaFold预测植物和耐热藻类中甘油酸激酶（GLYK）的3D结构，发现植物GLYK在高温下三个柔性环会变形，通过将藻类的刚性环替换到植物酶中，成功制造出在65°C下仍稳定的杂交酶，为培育耐热作物铺平道路。

Scientists are using AlphaFold in their research to strengthen an enzyme that’s vital to photosynthesis, paving the way for more heat-tolerant crops. As global warming accompanies more droughts and heatwaves, harvests of some staple crops are shrinking. But less visible is what is happening inside these plants, where high heat can break down the molecular machinery that keeps them alive. At the heart of that machinery lies a sun-powered process that supports virtually all life on Earth: photosyn
