Acetoacetate and acetate, intermediates in glutarate catabolism.
The labeling patterns found in tissue glutamate, aspartate, and alanine after administration of glutaric acid-3-Cl4 to male rats (1) indicated that the major catabolic route of glutarate is via acetate (2) and not via a direct conversion to the carbon chain of cu-ketoglutarate (3-5). In further studies on the metabolism of glutarate-3-C14 in rats, we have observed the formation of urinary acety...
متن کاملEnzymatic condensation of acetate to acetoacetate in liver extracts.
* The trichloroacetic acid extracts were first acidified with sulfuric acid3 and kept overnight at 38” for decarboxylation of acetoacetate. The fluid was then neutralized with sodium hydroxide and phosphate, and the acetone distilled by the procedure of Folin.4 Acetone was determined calorimetrically by the method of Behre.6 Analogous results were obtained with the determination procedure of Le...
متن کاملIdentification of cyclic intermediates in Azorhizobium caulinodans nicotinate catabolism.
In wild-type Azorhizobium caulinodans ORS571, nicotinate served both as anabolic substrate for NAD+ production and as catabolic substrate for use as the N source. Catabolic enzyme activities were greatest from cultures grown with nicotinate as the N source and least when cultures were grown with ammonium as the N source. Vector insertion mutants unable to catabolize nicotinate (nic::Vi mutants)...
متن کاملAcetoacetate Formation in Liver
In 1944, Weinhouse et al. (1) reported that the incubation of carboxyllabeled octanoate with rat liver slices yielded acetoacetate in which the carboxyl and carbonyl carbons were equally labeled. Random condensation of 2-carbon units resulting from ,8 oxidation was therefore offered by these workers as a possible mechanism for the formation of acetoacetic acid from octanoate. The conversion of ...
متن کاملMetabolism of basic amino acids in Pseudomonas putida. Intermediates in L-arginine catabolism.
y-Guanidinobutyrate amidinohydrolase, the third enzyme of L-arginine catabolism in Pseudomonas putida, has been purified 6%fold from extracts of cultures grown on L-arginine. Synthesis of the amidinohydrolase is induced by growth on L-arginine or y-guanidinobutyrate, but not by growth on y-aminobutyrate or on urea plus DL-malate. Hydrolysis of y-guanidinobutyrate to y-aminobutyrate and urea pro...
