Isovaleryl-CoA dehydrogenase is the assembly of '''<scene name='82/829361/2asymunit/1'>two asymmetric units</scene>''' each composed of '''two chains <scene name='82/829361/Chainea_asymunit/2'>A</scene> and <scene name='82/829361/Chaineb_asymunit/1'>B</scene>''' linked by a <scene name='82/829361/Ligand_asymunit/1'>ligand</scene> (Dihydroflavine-Adenine Dinucleotide also known as [https://pubchem.ncbi.nlm.nih.gov/compound/Dihydroflavine-adenine-dinucleotide FADH2] ). Each of the two chains A and B are composed of 388 amino acids. An asymmetric unit is therefore composed of 776 amino acids and has a molecular weight of 86233.70 Da.

1% of the unit's amino acid have incomplete sidechains, which means that there are 11 missing residue in the assymetric unit.<ref>https://oca.weizmann.ac.il/oca-docs/fgij/fg.htm?mol=4iv6</ref>

Isovaleryl-CoA dehydrogenase from Mycobacterium smegmatis assymetric unit is composed of two chains. These two chains are sequence-identical. 765 amino acid alpha carbons are present in the model. 11 (1%) have incomplete sidechains, which means that there are 11 missing residue in the assymetric unit. The unit contains 6 580 atoms, with 5 different atoms: C, N, O, P, S.

The two chains A and B of the isovaleryl-CoA dehydrogenase are linked by a <scene name='82/829361/Ligand_asymunit/1'>ligand</scene> (Dihydroflavine-Adenine Dinucleotide also known as [https://pubchem.ncbi.nlm.nih.gov/compound/Dihydroflavine-adenine-dinucleotide FADH2] ).

The assymetric unit also contains 2 ligands: 2FDA, Dihydroflavine-adenine dinucleotide.

The protein is a tetramer, the surface between the two monomers of a single dimer of an acyl-CoA dehydrogenase contains the FAD binding sites and has extensive bonding interactions. There are 2 active sites in the tetramer, each of these 2 sites contains a FAD molecule and an acyl-CoA substrate binding site. <ref>https://en.wikipedia.org/wiki/Flavin_adenine_dinucleotide</ref>
