Abstract

The Raman spectra of droplets of the low-complexity domain of an RNA-binding protein (Pbp1 LC) were measured to investigate the mechanism of the disappearance of Pbp1 LC droplets in oxidative environments. Raman quantification analysis indicated that the Pbp1 LC concentration in the droplets decreased with the addition of hydrogen peroxide. It was directly confirmed from the methionine band that the methionine residues were oxidized by hydrogen peroxide. We quantitatively evaluated the relationship between the degree of the methionine oxidation and the Pbp1 LC concentration in the droplets and showed that the droplet dissipation is induced by the methionine oxidation.

蛋氨酸氧化及其对 Pbp1 相分离液滴溶解的促进作用的拉曼定量分析
测量了 RNA 结合蛋白低复杂度结构域(Pbp1 LC)液滴的拉曼光谱,以研究 Pbp1 LC 液滴在氧化环境中消失的机理。拉曼定量分析表明,液滴中的 Pbp1 LC 浓度随着过氧化氢的加入而降低。从蛋氨酸带直接证实了蛋氨酸残基被过氧化氢氧化。我们定量评估了蛋氨酸氧化程度与液滴中 Pbp1 LC 浓度之间的关系,结果表明蛋氨酸氧化诱导了液滴的消散。

期刊介绍: Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
