IMPDH quaternary structures include multiunit complexes, such as <scene name='82/823089/Quaternary_view/1'>tetramers</scene>, extended octamers, and compacted octamers. These quaternary structures are created through the binding of multiple subunits of <scene name='82/823089/Tertiary_structure/1'>tertiary</scene> structures, that are strengthened and structurally formed through hydrogen-bonding, Cysteine-Cysteine disulfide bonds, and hydrophobic interactions. Different quaternary forms of IMPDH relate to the kinetic favorability of the IMPDH mechanism as Bateman domain allosteric binding sites and competitive nature changes with unit composition. | IMPDH quaternary structures include multiunit complexes, such as <scene name='82/823089/Quaternary_view/1'>tetramers</scene>, extended octamers, and compacted octamers.

This <scene name='82/823089/Space-filled/2'>space-filled view</scene> helps show the Van der Waals interactions and areas for movement within the structure. The ability for monovalent cations to move within the charged tunnel with the phosphate chain directly relates to activation levels. | This <scene name='82/823089/Space-filled/2'>space-filled view</scene> helps show the Van der Waals interactions and areas for movement within the structure. The ability for monovalent cations to move within the charged tunnel with the phosphate chain directly relates to activation levels. The phosphate chain relates to the ligands that further interact with the binding site to form the covalent intermediate, E-XMP*. | ||
<scene name='82/823089/Hydrophobicity_view/1'>Hydrophobicity view</scene> Purple represents polar molecules and gray represents hydrophobic molecules. The hydrophobicity is within the interior of the molecule as the hydrophilic residues are able to interact in a physiological environment. | <scene name='82/823089/Hydrophobicity_view/1'>Hydrophobicity view</scene> Purple represents polar molecules and gray represents hydrophobic molecules.
