The role of positively charge poly-L-lysine in the formation of high ...

The most common role for lysine is proteinogenesis. Lysine frequently plays an important role in protein structure. Since its side chain contains a positively charged group on one end and a long hydrophobic carbon tail close to the backbone, lysine is considered somewhat amphipathic. For this reason, lysine can be found buried as well as more commonly in solvent channels and on the exterior of proteins, where it can interact with the aqueous environment. Lysine can also contrib… Web11 oct. 2024 · Lysine side chains participate in geometrical arrangements involving like-charge ion pairing in 423 protein crystal structures in the PDB.
