Plant Aromatic Prenyltransferases: Tools for Microbial Cell Factories

Area of Science:

• Biochemistry
• Plant Biotechnology
• Metabolic Engineering

Background:

• Prenylation of aromatic compounds like flavonoids and stilbenoids by prenyltransferases (PTs) is crucial for producing bioactive molecules in plants.
• These prenylated compounds offer health benefits and industrial potential, but their low natural abundance hinders exploitation.
• Microbial cell factories present a promising avenue for sustainable and cost-effective production of these valuable compounds.

Purpose of the Study:

• To review current knowledge on plant aromatic prenyltransferases (PTs).
• To discuss strategies for optimizing prenylated aromatic compound production using microbial cell factories.
• To identify and address limitations in current production methods.

Main Methods:

• Literature review of plant prenyltransferases and their role in aromatic compound biosynthesis.
• Analysis of strategies for engineering microbial hosts for prenylation.
• Identification of challenges, such as prenyl donor availability, in microbial production systems.

Main Results:

• Plant PTs are key enzymes for synthesizing diverse prenylated aromatic compounds.
• Microbial cell factories offer a viable platform for producing these compounds.
• Limited availability of prenyl donor substrates is a significant bottleneck in microbial production.

Conclusions:

• Harnessing plant PTs in microbial systems is a sustainable strategy for producing high-value prenylated compounds.
• Overcoming substrate limitations is critical for efficient industrial-scale production.
• Further research into PTs and metabolic engineering will enhance the economic viability of these compounds.
