Application
聚甘氨酸已被用作外部强度标准品，用于测量交叉极化 (CP) 核磁共振 (NMR) 谱测量 和离子迁移质谱。适用于作为紫外共振拉曼光谱研究的模型。
Biochem/physiol Actions
多甘氨酸以两种形式存在，即具有反平行 β-片状结构和延伸 31 螺旋的多聚甘氨酸 II (PGII)。它是一种最灵活的多肽，具有最小的空间位阻，在锂离子存在下溶解度增加。存在于哺乳动物和植物中。与叶绿体膜蛋白 Toc5 相关的多聚甘氨酸伸展对于囊膜分选是必需的。
Preparation Note
通过磷酸化制备。

Poly-L-lysine is known to have three different secondary structures depending on solvent conditions because of its flexible nature. In previous work (Kambara et al., Phys Chem Chem Phys 2008, 10, 5042-5044), we observed two different types of structural changes in

Friction within globular proteins or between adhering macromolecules crucially determines the kinetics of protein folding, the formation, and the relaxation of self-assembled molecular systems. One fundamental question is how these friction effects depend on the local environment and in particular

The structure of the sodiated peptide GGGGGGGG-Na(+) or G(8)-Na(+) was investigated by infrared multiple photon dissociation (IRMPD) spectroscopy and a combination of theoretical methods. IRMPD was carried out in both the fingerprint and N-H/O-H stretching regions. Modeling used the polarizable
