Abstract

This study showed that Bombyx mori silk protein could be selectively induced to fold into fibrils dominated by either cross- or parallel-beta-sheet structure, where the beta-strands arrange perpendicular or parallel to the long fibril axis, incubated in ethanol-water quiescently or in water under shear.

摘要

这项研究表明，在乙醇-水静置或水剪切条件下，家蚕丝蛋白可以选择性地诱导形成以交叉或平行β-折叠结构为主的纤维，其中β-链垂直或平行于长纤维轴排列。
