Targeting homodimeric enzymes is a promising therapeutic strategy. Inhibiting protein-protein interactions at enzyme interfaces offers selective drug development opportunities for various diseases.
Area of Science:
- Biochemistry
- Structural Biology
- Drug Discovery
Background:
- Protein function is often regulated by quaternary structure and oligomeric complex formation.
- Protein-protein interactions are key targets for therapeutic intervention.
- The Protein Data Bank highlights the significance of multimeric protein complexes.
Purpose of the Study:
- To review homodimeric enzymes as drug targets.
- To explore strategies for inhibiting enzyme dimerization.
- To present techniques for studying these interactions.
Main Methods:
- Review of structural features of dimeric enzymes.
- Analysis of existing dimerization inhibitors (peptides, small molecules).
- Discussion of techniques for studying inhibitor binding and mechanisms.
Main Results:
- Enzyme interfaces offer selective and specific drug targeting due to lower amino acid conservation compared to active sites.
- Two main classes of dimerization inhibitors exist: peptide-based and small molecule inhibitors.
- Inhibition can be achieved by interfering with dimer stability.
Conclusions:
- Homodimeric enzymes represent viable drug targets.
- Targeting protein-protein interfaces provides a route for selective therapeutic development.
- Diverse techniques are available for studying these complex biological systems.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
