Homodimer
Homodimer — A dimer composed of two identical subunits held together by covalent or non-covalent interactions.
What Is a Homodimer?
A homodimer is a complex of two identical peptide or protein molecules. Homodimerization can be functional (designed dimeric peptides) or an impurity (unwanted disulfide-linked dimers). Homodimeric peptide drugs and designed dimeric AMPs often show enhanced activity compared to their monomeric forms.
Context
- Detection: SEC peak at approximately double the monomer elution volume
- Designed: Parallel or antiparallel dimeric peptides via cross-linking or template assembly
- Impurity: Cys-Cys intermolecular disulfide. Prevented by capping with iodoacetamide
