功能和蛋白质-水相互作用

Functionality and Protein-Water Interactions

J. C. Phillips

摘要:

蛋白质的结构呈现出由螺旋和环组成的二级元件。几个水的疏水性尺度与两个重复蛋白质的功能的比较表明,这些二级元素具有水诱导的中程秩序,有时是相似的,但也可以是互补的,结构顺序。这些迄今为止的“幻影”序参量的研究有望在蛋白质动力学理论的影响深远的增量改进。该理论的一个副产品是对不同疏水性尺度的可靠性的独立评估。

英文摘要:

The structures of proteins exhibit secondary elements composed of helices and loops. Comparison of several water-only hydrophobicity scales with the functionalities of two repeat proteins shows that these secondary elements possess water-induced medium-range order that is sometimes similar, but can also be complementary, to structural order. Study of these hitherto "phantom" order parameters promises far-reaching incremental improvements in the theory of protein dynamics. A by-product of the theory is an independent evaluation of the reliability of different hydrophobicity scales.
