The formation and function of plant metabolons

Area of Science:

• Biochemistry
• Molecular Biology
• Plant Science

Background:

• Metabolons are dynamic enzyme complexes crucial for metabolic pathways.
• Substrate channeling via metabolons enhances efficiency in plant metabolic processes.
• While many plant metabolons are proposed, only four substrate channels are experimentally confirmed.

Approach:

• Reviewing the history of enzyme-enzyme assembly studies, focusing on plant metabolons.
• Examining current methodologies for characterizing plant metabolons and substrate channeling.
• Investigating novel approaches like liquid droplet phase separation and enzyme chemotaxis from non-plant systems.

Key Points:

• Plant metabolon assembly often involves interactions with cellular structural elements.
• Diverse mechanisms of metabolon assembly require exploration beyond current models.
• Subcellular mass spectrometry, proteomics, and advanced computational biology offer new avenues.

Conclusions:

• Current understanding of plant metabolons is limited, particularly for those not reliant on structural interactions.
• Novel strategies are proposed to identify and characterize plant metabolons assembling through alternative mechanisms.
• Integrating advanced imaging, proteomics, and computational methods will expand knowledge of plant metabolon diversity and function.
