A method was designed to describe the helical structures of various levels of organization in proteins. The method makes it possible to characterize the sign of chirality/helicity and to quantify α-helices, 3₁₀-helices, and coiled-coil structures. The data is important for developing the earlier concept of sign-alternating chiral hierarchies of nucleic acid and protein structures. A sufficient condition for the method is the relative location of α-carbons in the helix. With this condition satisfied, the amount of information to be processed can be reduced by one order of magnitude. The method thus offers a clear benefit for processing large data sets.

确定螺旋和超螺旋蛋白质结构手性符号的方法

设计了一种方法来描述蛋白质中不同组织水平的螺旋结构。该方法可以表征手性/螺旋性的符号并量化 α 螺旋、3 ₁₀螺旋和卷曲螺旋结构。这些数据对于开发核酸和蛋白质结构的符号交替手性层次结构的早期概念很重要。该方法的充分条件是α-碳在螺旋中的相对位置。在满足这个条件的情况下，要处理的信息量可以减少一个数量级。因此，该方法为处理大型数据集提供了明显的好处。
