Spectrophotometric Studies on the Decarboxylation of & Keto Acids
Reaction 1 is catalyzed by an enzyme widely distributed in animal tissues and present in some plants (1). Oxalacetic carboxylase, which catalyzes Reaction 2, has been found in bacteria (2), pigeon liver (3), and, to some extent, in other animal tissues as well as in plants (4). Mehler et al.’ have partially purified this enzyme from Microcowus lysocleikticus. Acetoacetic carboxylase (Reaction 3...
متن کاملFungicidal activity of some o-nitrophenyl-hydrazones.
The antimycotic activity of 16 o-nitrophenylhydrazones against strains of Hansenula anomala, Saccharomyces cerevisiae, Candida parapsylosis, and Cryptococcus albidus was tested. All 16 compounds inhibited growth of the yeast strains. The inhibitory activity of the 4 methyl-derivatives substituted on the aromatic nucleus was particularly significant.
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...
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 کاملAntidepressant activity of some phenylaceticacid hydrazones and 2-chlorophenyl semicarbazones.
Fig, 1: Structure of phenylaceticacid hydrazones and 2-chlorophenylsemicarbazones. Antidepressant activity was evaluated in albino rats weighing 100 to 120 g, by Porsolt forcecll swimming test (4). Rats were individually placed in plexiglass cylinders (height 40 cm; diameter 18 cm), containing 15 cm of water maintained at 25°C. After 15 minutes they were removed to a 30°C drying room for 30 min...
