Intrinsically disordered proteins (IDPs) exist as dynamic conformational ensembles the behavior of which challenges the tenets of the protein structure-function paradigm. In a new study, Newcombe, Due et al. reveal a striking continuum in sensitivity to chirality: while folded complexes are under strong chiral constraints, progressively disordered complexes show decreased sensitivity to chirality.
内在无序蛋白(IDP)以动态构象集合的形式存在,其行为对蛋白质结构-功能范式的原则提出了挑战。在一项新研究中,纽科姆、杜等人揭示了对手性敏感性的一个显著连续体:虽然折叠复合物受到强烈的手性限制,但逐渐无序的复合物对手性的敏感性降低。
