what is a tetramer protein?
<answer> A tetrameric protein is a protein with a quaternary structure of four subunits. <context> The formation of the sorbitol dehydrogenase tetramer from its monomers via dimers. A tetrameric protein is a protein with a quaternary structure of four subunits (tetrameric). Homotetramers have four identical subunits (such as glutathione S-transferase), dimers of dimers contain two heterodimer subunits (such as hemoglobin), and heterotetramers are complexes of four different subunits.
