通过对β-夹心蛋白二级结构空间组织的计算机分析,我们发现了某些由氢键连接的连续链,我们称之为“链子”。对来自69个不同超家族的491个蛋白质结构中链子排列的分析揭示了链子排列的严格限制和我们所说的“典型超基序”的形成。“六个这样的超级图案占所有观察到的结构的大约90%。简单的几何规则,说明这些超图案的形成。
From a computer analysis of the spatial organization of the secondary structures of beta-sandwich proteins, we find certain sets of consecutive strands that are connected by hydrogen bonds, which we call "strandons." The analysis of the arrangements of strandons in 491 protein structures that come from 69 different superfamilies reveals strict regularities in the arrangements of strandons and the formation of what we call "canonical supermotifs." Six such supermotifs account for approximately 90% of all observed structures. Simple geometric rules are described that dictate the formation of these supermotifs.
