Thiolase

spinqualitylabelsall models Human 3-ketoacyl-CoA complex with CoA and ethylene glycol(PDB code 4c2j). Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Two different classes of thiolases are found. Degrative thiolase like 3-ketoacyl-CoA thiolase (KCT) is involved in fatty acid β oxidation. Biosynthetic thiolases like acetoacetyl-CoA thiolase (ACT) are involved in the thiolysis of acetoacetyl-CoA. For Bacterial thiolase see Bacterial thiolase Structural highlights The active site of 3-ketoacyl-CoA thiolase contains CoA. Water molecules shown as red spheres.
