挫折、功能和折叠

Frustration, function and folding

Diego U. Ferreiro, Elizabeth A. Komives, Peter G. Wolynes

摘要:

天然蛋白质分子是特殊的聚合物。这些物体显然是由随机的氨基酸串编码的,它们执行着明确的物理任务,而这些任务是很难通过简单的偶然发现的。精确的折叠、特异性结合、强大的催化作用是大多数多肽不显示的基本化学活性的例子,并且被认为是蛋白质自然历史的结果。功能是生物学中的一个真正概念,是进化的核心,经常与物理限制相冲突。在一个循环系统中,找出不同目标之间的挫折感,可以让我们对塑造生物信息编码的机会和必要性有一个基本的认识。

英文摘要:

Natural protein molecules are exceptional polymers. Encoded in apparently random strings of amino-acids, these objects perform clear physical tasks that are rare to find by simple chance. Accurate folding, specific binding, powerful catalysis, are examples of basic chemical activities that the great majority of polypeptides do not display, and are thought to be the outcome of the natural history of proteins. Function, a concept genuine to Biology, is at the core of evolution and often conflicts with the physical constraints. Locating the frustration between discrepant goals in a recurrent system leads to fundamental insights about the chances and necessities that shape the encoding of biological information.
