生物通报道：riboswitch(一些信使RNA内的调控元素）是一种控制蛋白表达的机制，功能好像“按钮”，被按后会阻止目的蛋白的表达。最近，波恩大学生命和医学科学中心研究人员得到一种发卡状RNA分子（hairpin-shaped RNA），可以区分riboswitch的开启和关闭状态。

Comparison of the folding mechanisms of proteins with similar structures but very different sequences can provide fundamental insights into the determinants of protein folding mechanisms. Despite very ...
