SARS-CoV-2 Is an Electricity-Driven Virus

Area of Science:

• Biophysics
• Molecular Biology
• Virology

Background:

• The SARS-CoV-2 pandemic presents significant biological challenges.
• Electrical forces are proposed as a ubiquitous driver of diverse biological events.
• Understanding viral protein function is crucial for pandemic response.

Purpose of the Study:

• To investigate the electrical regulation of SARS-CoV-2 structural proteins.
• To explore the role of liquid-liquid phase separation (LLPS) in viral protein activity.
• To connect the broader concept of electrical forces to viral mechanisms.

Main Methods:

• Analysis of electrical properties of SARS-CoV-2 structural proteins (spike, nucleocapsid, membrane, envelope).
• Examination of how LLPS influences protein functions.
• Review of multivalent, π-cation, and π-π electrical interactions driving phase separation.

Main Results:

• Electrical forces play a regulatory role in spike, nucleocapsid, membrane, and envelope proteins.
• LLPS is identified as a key mechanism controlling the activity of these viral proteins.
• Specific electrical interactions (multivalent, π-cation, π-π) are implicated in driving LLPS.

Conclusions:

• Electrical forces are fundamental to the function of SARS-CoV-2 structural proteins.
• LLPS, driven by specific electrical interactions, is a critical regulatory process for the virus.
• This perspective broadens the understanding of viral mechanisms through biophysical principles.
