- Direct observation of the detailed conformational fluctuations of a single protein molecule en route to its folded state has so far been realized only in silico. We have used single-molecule force spectroscopy to study t...
- How Fast-Folding Proteins Fold
[作者:Lindorff-Larsen, K; Piana, S; Dror, RO; Shaw, DE,期刊:Science, 页码:517-520 , 文章类型: Article,,卷期:2011年334-6055]
- An outstanding challenge in the field of molecular biology has been to understand the process by which proteins fold into their characteristic three-dimensional structures. Here, we report the results of atomic-level mol...
- Impacts of the Cretaceous Terrestrial Revolution and KPg Extinction on Mammal Diversification
