Apomorphine Targets the Pleiotropic Bacterial Regulator Hfq

Area of Science:

• Microbiology
• Molecular Biology
• Drug Discovery

Background:

• The Hfq protein is a key bacterial regulator controlling gene expression, RNA decay, and adaptation.
• Hfq's C-terminal region (Hfq-CTR) forms amyloid structures, influencing bacterial survival and antibiotic response.
• Green tea compound EGCG remodels Hfq-CTR amyloid fibrils, suggesting therapeutic potential.

Purpose of the Study:

• To investigate apomorphine's potential as an antibacterial agent by targeting Hfq protein.
• To explore apomorphine's effect on Hfq-CTR amyloid formation and bacterial adaptation.

Main Methods:

• Investigated apomorphine's interaction with Hfq-CTR.
• Assessed apomorphine's impact on Hfq-CTR amyloid formation.
• Evaluated apomorphine's antibacterial activity and effect on bacterial adaptation.

Main Results:

• Apomorphine inhibits Hfq-CTR amyloid formation.
• Apomorphine demonstrates potential as a novel antibacterial compound.
• Repurposing apomorphine could offer a new strategy to combat bacterial infections.

Conclusions:

• Apomorphine's ability to inhibit Hfq amyloid formation presents a novel antibacterial mechanism.
• Apomorphine may be repurposed as an antibiotic to block bacterial adaptation and treat infections.
