In structural biology, a protein subunit or subunit protein is a single protein molecule that assembles (or coassembles) with other protein molecules to form a protein complex: a multimeric or oligomeric protein. Many naturally-occurring proteins and enzymes are multimeric. Examples include: oligomeric: hemoglobin, DNA polymerase, nucleosomes and multimeric: ion channels, microtubules and other cytoskeleton proteins. The subunits of a multimeric protein may be identical, homologous or totally dissimilar and dedicated to disparate tasks. In some protein assemblies, one subunit may be referred to as a regulatory subunit and another as a catalytic subunit. An enzyme composed of both regulatory and catalytic subunits when assembled is often referred to as a holoenzyme. One subunit is made of one polypeptide chain. A polypeptide chain has one gene coding for it – meaning that a protein must have one gene for each unique subunit.
