The formation of the sorbitol dehydrogenase tetramer from its monomers via dimers. A<unk>  is a protein with a quaternary structure of four subunits<unk> . Homotetramers have four identical subunits (such as glutathione S-transferase), and heterotetramers are complexes of different subunits. A<unk> an be assembled as dimer of dimers with two homodimer subunits (such as sorbitol dehydrogenase), or two heterodimer subunits (such as hemoglobin).
