The effect of cations on the decarboxylation of oxalacetic acid.
In connection with studies on the /3-keto acid carboxylases of plants (1, 2), the effects of metal ions on the decarboxylation of oxalacetic acid, in the presence and absence of enzyme, were studied. In confirmation of Krebs (3) the decarboxylation was found to be accelerated by a variety of polyvalent cations. It was also observed that the enzyme oxalacetic carboxylase from parsley roots, whic...
متن کاملEnzymatic decarboxylation of oxalic acid.
Large quantities of oxalic acid accumulate in the cell sap of various plants and as a major product of carbohydrate metabolism by many molds. A recent investigation in our laboratory revealed that oxalic acid was produced from oxalacetic acid by an enzyme system which was isolated from the mycelia of Aspergillus niger (1). It was also demonstrated that oxalic acid was converted to formic acid a...

As part of a larger project dealing with an in vestigation of amino acid and protein metabolism in leukemia, a study was undertaken to determine those enzymes concerned with amino acid anabo lism and catabolism as they occur in selected tis sues. Several review papers (@,4, 11, 1@)have ade quately summarized our present knowledge of the metabolism of white blood cells (WBC) in leuke mia. Howeve...
متن کاملEnzymatic Decarboxylation of Oxalic Acid* by William
Although it has been recognized that oxalic acid is decomposed by a variety of microorganisms (2-6), relatively little is known of the details of oxalic acid metabolism. The present study represents an attempt to establish the mechanism of oxalate degradation at the enzyme level by the use of a bacterium isolated from soil. Partially purified enzyme preparations obtained from the organism catal...
متن کاملStereochemistry of decarboxylation of trans-4-hydroxycinnamic acid by Aerobacter.
The stereochemistry of the decarboxylation of trans-p-coumaric acid to 4-hydroxystyrene by Aerobacter aerogenes has been examined. The decarboxylation has been found to proceed with retention of the geometry about the trans-substituted double-bond.
