Wikipedia
Protomer
In structural biology, a protomer is the structural unit of an oligomeric protein. It is the smallest unit composed of at least two different protein chains that form a larger hetero-oligomer by association of two or more copies of this unit. The term was introduced by Chetverin to make nomenclature in the Na/K-ATPase enzyme unambiguous. This enzyme is composed of two subunits: a large, catalytic α subunit, and a smaller glycoprotein β subunit (plus a proteolipid, called γ-subunit). At the time it was unclear how many of each work together. In addition, when people spoke of a dimer, it was unclear whether they were referring to αβ or to (αβ)2. Chetverin suggested to call αβ a protomer and (αβ)2 a diprotomer. Protomers usually arrange in cyclic symmetry to form closed point group symmetries. In chemistry, a so-called protomer is a molecule which displays tautomerism due to position of a proton.

Protomer
In structural biology, a protomer is the structural unit of an oligomeric protein. A protomer can be a protein subunit or several different subunits, that assemble in a defined stoichiometry to form an oligomer. The protomer is the smallest subset of different subunits that form the oligomer. The protomers usually arrange in cyclic symmetry to form closed point group symmetries. Protomers are the main subunit in a viral capsid. Different polypeptide chains are conventionally designated by Greek letters. In the following examples, the number of each subunit in the oligomeric complex is indicated by the subscript number, similarly to a chemical formula of a compound consisting of elements.
