摘要: In one aspect, the invention relates to a peptide that forms a calcium-dependent hydrogel using a rationally engineered beta roll peptide. In the absence of calcium, the peptide is intrinsically disordered. Upon addition of calcium, the peptide forms a corkscrew-like structure. In one embodiment, one face of the beta roll is mutated to comprise leucine residues. In some embodiments, a leucine zipper forming helical domain to the engineered beta roll forms hydrogels by physical cross-linking in calcium rich environments.

摘要翻译: 在一个方面,本发明涉及使用合理工程化的β卷肽形成钙依赖性水凝胶的肽。 在不存在钙的情况下,肽本质上是无序的。 加入钙后,肽形成螺塞状结构。 在一个实施方案中,β卷的一个表面被突变以包含亮氨酸残基。 在一些实施方案中,形成螺旋结构域的亮氨酸拉链与工程化的β型辊在富含钙的环境中通过物理交联形成水凝胶。
