A new protein evolution mechanism, structural capacitance, creates microstructure in disordered regions, enabling rapid evolutionary change. This mechanism is linked to human diseases and protein engineering.
Area of Science:
- Molecular Biology
- Evolutionary Biology
- Biochemistry
Background:
- Canonical protein evolution relies on gene duplication and mutations.
- Post-translational modifications also influence protein structure and function.
Purpose of the Study:
- To identify novel mechanisms of protein evolution.
- To investigate the role of structural capacitance in rapid evolution and disease.
Main Methods:
- Survey of the human mutation database.
- Analysis of protein microstructure generation in disordered regions.
Main Results:
- Identified "structural capacitance" as a de novo microstructure generation mechanism.
- Structural capacitance facilitates rapid, saltatory evolution.
- Linked protein microstructure generated by this mechanism to human disease pathogenesis.
Conclusions:
- Structural capacitance offers a distinct pathway for rapid protein evolution.
- This mechanism presents a trade-off between evolutionary potential and disease risk.
- Structural capacitance has implications for understanding protein fold diversification and synthetic protein design.
