Liquid-liquid phase separation in microorganisms: Insights into existence, functions, and applications

Area of Science:

• Microbiology
• Biochemistry
• Cell Biology

Background:

• Liquid-liquid phase separation (LLPS) is crucial for cellular organization in microorganisms, but less understood than in mammalian cells.
• Microbial LLPS involves intrinsically disordered proteins and is linked to environmental adaptation.
• Limited research exists on LLPS formation and regulation in microorganisms.

Purpose of the Study:

• To review and integrate current knowledge on LLPS in microorganisms.
• To discuss the role of LLPS in microbial environmental adaptation and cellular processes.
• To highlight LLPS as a target for synthetic biology and antimicrobial therapies.

Main Methods:

• Literature review integrating diverse studies on microbial LLPS.
• Analysis of the role of intrinsically disordered proteins in LLPS.
• Examination of LLPS in response to environmental cues (temperature, pH, nutrients).

Main Results:

• Microorganisms utilize LLPS to sense and respond to environmental changes.
• LLPS regulates key cellular processes including cell division, protein synthesis, and metabolism.
• Intrinsically disordered proteins are key drivers of microbial LLPS and adaptation.

Conclusions:

• LLPS is a vital mechanism for microbial survival, adaptation, and regulation.
• LLPS presents significant opportunities for synthetic biology and developing new antimicrobial strategies.
• Further research is needed on molecular mechanisms, biotechnological applications, and therapeutic targets.
