Decarboxylation of 2-keto fatty acids by brain
An enzyme system consisting of washed acetone powder of pig brain, adenosine triphosphate, nicotinamide adenine dinucleotide, magnesium, fumaric acid, and ascorbic acid was found to catalyze the oxidative decarboxylation of 2-ketostearic acid. The products were carbon dioxide and heptadecanoic acid....

| Summary: | An enzyme system consisting of washed acetone powder of pig brain, adenosine triphosphate, nicotinamide adenine dinucleotide, magnesium, fumaric acid, and ascorbic acid was found to catalyze the oxidative decarboxylation of 2-ketostearic acid. The products were carbon dioxide and heptadecanoic acid. Washing the enzyme powder with ethylenediaminetetraacetate and other chelating agents destroyed the activity. Further properties of the enzyme system are described. It is believed that this enzyme system accounts in part for the 1-carbon degradation route for brain fatty acids. |
