Chains	Enzyme Name	Description	Catalytic Residues
A	3,2-trans-enoyl-CoA isomerase (mitochondrial) M-CSA #341	Delta3-delta2-enoyl CoA isomerase (enoyl-CoA isomerase) is a mitochondrial enzyme, in this case from human, catalyses the conversion of 3-cis-enoyl-CoA or 3-trans-enoyl-CoA into 2-trans-enoyl-CoA. This is involved in an auxiliary pathway of fatty acid degradation, and the product is subsequently metabolised further by other enzymes of the pathway. Enoyl-CoA isomerases use fatty acyl substrates with side-chains ranging from C6 to C16. The reaction used as example uses a C12 compund as substrate	Defined by 4 residues: LEU:A-66GLY:A-111ASN:A-135GLU:A-136 \| Explore in 3D: M-CSA Motif Definition Search M-CSA Motif EC: 5.3.3.8 (PDB Primary Data) Search M-CSA Motif + EC 5.3.3.8
