Human liver long-chain 3-hydroxyacyl-coenzyme A dehydrogenase is a multifunctional membrane-bound beta-oxidation enzyme of mitochondria.
Carpenter K., Pollitt R.J., Middleton B.
We have purified to homogeneity the long-chain specific 3-hydroxyacyl-CoA dehydrogenase from mitochondrial membranes of human infant liver. The enzyme is composed of non-identical subunits of 71 kDa and 47 kDa within a native structure of 230 kDa. The pure enzyme is active with 3-ketohexanoyl-CoA ... >> More
We have purified to homogeneity the long-chain specific 3-hydroxyacyl-CoA dehydrogenase from mitochondrial membranes of human infant liver. The enzyme is composed of non-identical subunits of 71 kDa and 47 kDa within a native structure of 230 kDa. The pure enzyme is active with 3-ketohexanoyl-CoA and gives maximum activity with 3-ketoacyl-CoA substrates of C10 to C16 acyl-chain length but is inactive with acetoacetyl-CoA. In addition to 3-hydroxyacyl-CoA dehydrogenase activity, the enzyme possesses 2-enoyl-CoA hydratase and 3-ketoacyl-CoA thiolase activities which cannot be separated from the dehydrogenase. None of these enzymes show activity with C4 substrates but all are active with C6 and longer acyl-chain length substrates. They are thus distinct from any described previously. This human liver mitochondrial membrane-bound enzyme catalyses the conversion of medium- and long-chain 2-enoyl-CoA compounds to: 1) 3-ketoacyl-CoA in the presence of NAD alone and 2) to acetyl-CoA (plus the corresponding acyl-CoA derivatives) in the presence of NAD and CoASH. It is therefore a multifunctional enzyme, resembling the beta-oxidation enzyme of E. coli, but unique in its membrane location and substrate specificity. We propose that its existence explains the repeated failure to detect any intermediates of mitochondrial beta-oxidation. << Less

Substrate specificities of 3-oxoacyl-CoA thiolase A and sterol carrier protein 2/3-oxoacyl-CoA thiolase purified from normal rat liver peroxisomes. Sterol carrier protein 2/3-oxoacyl-CoA thiolase is involved in the metabolism of 2-methyl-branched fatty acids and bile acid intermediates.

The two main thiolase activities present in isolated peroxisomes from normal rat liver were purified to near homogeneity. On sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the first enzyme preparation displayed a single band of 41 kDa that was identified as 3-oxoacyl-CoA thiolase A (thiolase A) by N-terminal amino acid sequencing. The second enzyme preparation consisted of a 58- and a 46-kDa band. The 58-kDa polypeptide reacted with antibodies raised against either sterol carrier protein 2 or the thiolase domain of sterol carrier protein 2/3-oxoacyl-CoA thiolase (SCP-2/thiolase), formerly also called sterol carrier protein X, whereas the 46-kDa polypeptide reacted only with the antibodies raised against the thiolase domain. Internal peptide sequencing confirmed that the 58-kDa polypeptide is SCP-2/thiolase and that the 46-kDa polypeptide is the thiolase domain of SCP-2/thiolase. Thiolase A catalyzed the cleavage of short, medium, and long straight chain 3-oxoacyl-CoAs, medium chain 3-oxoacyl-CoAs being the best substrates. The enzyme was inactive with the 2-methyl-branched 3-oxo-2-methylpalmitoyl-CoA and with the bile acid intermediate 24-oxo-trihydroxycoprostanoyl-CoA. SCP-2/thiolase was active with medium and long straight chain 3-oxoacyl-CoAs but also with the 2-methyl-branched 3-oxoacyl-CoA and the bile acid intermediate. In peroxisomal extracts, more than 90% of the thiolase activity toward straight chain 3-oxoacyl-CoAs was associated with thiolase A. Kinetic parameters (Km and Vmax) were determined for each enzyme with the different substrates. Our results indicate the following: 1) the two (main) thiolases present in peroxisomes from normal rat liver are thiolase A and SCP-2/thiolase; 2) thiolase A is responsible for the thiolytic cleavage of straight chain 3-oxoacyl-CoAs; and 3) SCP-2/thiolase is responsible for the thiolytic cleavage of the 3-oxoacyl-CoA derivatives of 2-methyl-branched fatty acids and the side chain of cholesterol. << Less
