Protein folding stability and binding interactions through the lens of evolution: a dynamical perspective

Area of Science:

• Protein dynamics and evolution
• Computational biology
• Structural biology

Background:

• Protein function relies on correct 3D folding, yet evolution has favored flexibility for adaptation.
• Nature balances protein folding stability with evolving new functions through molecular interactions.
• Understanding how evolution molds protein dynamics is crucial for deciphering functional landscapes.

Purpose of the Study:

• To investigate how evolution shapes protein folding and functional landscapes from a conformational dynamics perspective.
• To highlight the role of dynamic allostery in protein evolution.
• To explore how protein anisotropic networks generate allosteric and epistatic interactions.

Main Methods:

• Review of recent computational and experimental studies.
• Analysis of conformational dynamics in protein evolution.
• Examination of protein anisotropic networks.

Main Results:

• Evolution has progressively increased protein flexibility to adapt to changing environments.
• Dynamic allostery plays a significant role in shaping protein functional evolution.
• Protein anisotropic networks are key to allosteric and epistatic interactions.

Conclusions:

• Conformational dynamics provide a critical lens for understanding protein evolution.
• Dynamic allostery is a fundamental mechanism by which evolution molds protein function.
• The study of protein networks reveals insights into the evolutionary basis of molecular interactions.
