Protamine and zinc binding-induced conformational effects on insulin analogs: an integrated experimental and computational study.

Insulin and its modified analogs play a critical role in the development and function of various insulin formulations, particularly concerning insulin's time-dependent action. Given that zinc promotes the formation of insulin hexamer, the most stable form, we aim to investigate the conformational dynamics of insulin analogs, specifically lispro and aspart, both in the absence and presence of zinc. Additionally, we seek to study their interactions with protamine, a key component of insulin formulations.
