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 Function Two different classes of thiolases are found. Degrative thiolase like 3-ketoacyl-CoA thiolase (KCT) is involved in fatty acid beta oxidation[1]. Biosynthetic thiolases like acetoacetyl-CoA thiolase (ACT) or acetyl-CoA acetyltransferase are involved in the thiolysis of acetoacetyl-CoA[2]. For bacterial thiolase see Bacterial thiolase SCP2-thiolase converts in the bile acid synthesis pathway 24-keto-THC-CoA into choloyl-CoA and propionyl-CoA[3]. For zebrafish thiolase see SCP2-thiolase. SCP is Sterol Carrier Protein. U34-tRNA-thiolase thiolates uridine 34 in tRNA anticodon loop which guarantees the fidelity of protein translation in archaea[4]. See also Mevalonate pathway Structural highlights The [5].
