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>''' | 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>'''. 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> | |||
The A chain is made up of <scene name='82/829361/Helixalphachaina_asymunit/1'>17 helices</scene> (involving 221 residues) and <scene name='82/829361/Betasheetchaina_asymunit/1'>14 beta-sheets</scene> (61 residues). | The A chain is made up of <scene name='82/829361/Helixalphachaina_asymunit/1'>17 helices</scene> (involving 221 residues) and <scene name='82/829361/Betasheetchaina_asymunit/1'>14 beta-sheets</scene> (61 residues). | ||

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 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> | 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.
