In biochemistry, a dimer is a macromolecular complex formed by two, usually non-covalently bound, macromolecules such as proteins or nucleic acids. (The word dimer has roots meaning "two parts", di- + -mer.) It is a quaternary structure of a protein.
A homodimer is formed by two identical molecules (a process called homodimerisation). A heterodimer is formed by two different macromolecules (called heterodimerisation).
Most dimers in biochemistry are not connected by covalent bonds. An example of a non-covalent heterodimer is the enzyme reverse transcriptase, which is composed of two different amino acid chains.[1] An exception is dimers that are linked by disulfide bridges such as the homodimeric protein NEMO.[2]
Some proteins contain specialized domains to ensure dimerization (dimerization domains).
