glycylglycine

Glycylglycine (Diglycine) 是一种简单的多肽，能够作为谷氨酰胺 (gamma-glutamyl) 的受体。

Tyrosyl-glycyl-glycine 是一种由脑啡肽酶释放的三肽，是一种代谢产物，由一个L-酪氨酸和两个甘氨酸残基按顺序连接而成。

Lysostaphin是一种具有强大抗葡萄球菌活性的化合物，通过三种不同的酶展现其酶促活性：glycylglycine endopeptidase、endo-β-N-acetyl glucosamidase和N-acetyl muramyl-L-alanine amidase。

CAY10679, an anionic oligopeptide-based bola-amphiphile, features a central hexane segment bordered by a glycylglycine group at each end, establishing pronounced hydrophilic and hydrophobic regions. This amphiphilic peptide's propensity for self-assembling into microtubes in aqueous acidic solutions has been explored. Such bola-amphiphiles hold significant potential in the development of nanotubes, nanovesicles, nanowires, and nanocarriers for drug delivery, among various bionanotechnology applications.
