Abstract
The isolated S-peptide (residues 1-20 of ribonuclease A) is known to show partial alpha-helix formation in aqueous solutions at low temperatures. We show here that the helix is limited to certain residues, including ones that are helical in the intact protein, and that a functional helix termination signal exists in the isolated peptide.
摘要
已知分离出的S肽（核糖核酸酶A的1-20位残基）在低温水溶液中会形成部分α-螺旋结构。我们在此表明，该螺旋仅限于某些残基，包括完整蛋白质中呈螺旋结构的残基，并且在分离出的肽中存在一个功能性螺旋终止信号。
