Size Matters: A Biophysical Perspective on Biomolecular Condensates in Bacteria.

Area of Science:

• Microbiology
• Biophysics
• Cell Biology

Background:

• Bacteria, unicellular organisms, lack membrane-bound organelles but possess internal organization mechanisms.
• Biomolecular condensates are emerging as key membraneless compartments driving cellular organization in bacteria.

Purpose of the Study:

• To review the biophysical features influencing bacterial condensate formation and stability.
• To present examples of endogenous bacterial condensates, their molecular drivers, and functions.
• To provide an overview of tools for studying and manipulating bacterial condensates.

Main Methods:

• Literature review of bacterial biophysics and condensate research.
• Analysis of molecular components and functional roles of endogenous condensates.
• Survey of current and prospective research tools for condensate manipulation.

Main Results:

• Bacterial cell size and internal crowding impact condensate nucleation and stability.
• Three distinct endogenous condensates are described with their molecular underpinnings.
• Various tools exist for studying and engineering bacterial condensates.

Conclusions:

• Bacterial condensates are crucial for cellular organization and function.
• Further research into bacterial condensates bridges biophysics, cell biology, and bioengineering.
