Abstract

An ultra-high-resolution NMR experiment for the measurement of intraresidue (1)H(i)-(15)N(i)-(13)C'(i) dipolar-chemical shift anisotropy relaxation interference is employed to extract information about local backbone geometries in intrinsically disordered proteins. The study of tumor suppressor BASP1 revealed a population shift of β-turn geometries at low pH conditions and a compaction of the BASP1 structural ensemble.

摘要

采用超高分辨率 NMR 实验测量残基内 (1)H(i)-(15)N(i)-(13)C'(i) 二极偶-化学位移各向异性弛豫干扰,以提取固有无序蛋白质中局部骨架几何形状的信息。对肿瘤抑制因子 BASP1 的研究表明,在低 pH 条件下,β-转角几何形状发生了种群转移,BASP1 结构集合发生了紧缩。
