Plasma Protein Labeled with Lysine-ε-c14
The metabolism of homologous plasma proteins, labeled with lysine-epsilon-C(14), after oral administration to dogs has been investigated. The speed of the various processes involved is indicated by the maximum rate of C(14) O(2) excretion which is attained within 1 to 4 hours, the prompt appearance of protein activity in the plasma and disappearance of non-protein activity from it, both virtual...
متن کاملIncorporation of C14-labeled substrates into violacein.
Previous studies on the physiological aspects of violacein biosynthesis (DeMoss and Evans, 1959) suggested that only L-tryptophan would serve as the primary source of carbon for pigment formation by Chromobacterium violaceum. In view of the pigment structure suggested by Ballantine et al. (1958), 5-[3-(5-hydroxyindolyl)]-3-(3-isatinyl)-2-pyrrolone, it seemed advisable to determine the actual so...
متن کاملDissimilation of C14-labeled glucose by Serratia marcescens.
Glucose containing radioactive carbon has been utilized in the study of the metabolic distribution of the various carbon atoms during dissimilation by the following organisms: Leuconostoc mesenteroides, (Gunsalus and Gibbs, J. Biol. Chem. 194, 871, 1952); Pseudomonas saccharophila, (Entner and Doudoroff, J. Biol. Chem. 196, 853, 1952); Pseudomonas fluorescens (Lewis et al., J. Biol. Chem., 216,...
متن کاملThe metabolism of ring-labeled L-thyroxine-C14 in vivo.
In the past, investigators have used thyroxine labeled either with JIP" in the 3',5'-position or with C14 in the carboxyl position to study the metabolism of thyroxine in vivo. Although these studies have yielded much valuable information, our knowledge about the metabolic fate of the ring structure in thyroxine is incomplete because both the 3'5'-IJ13 and the carboxyl-C14 are rapidly removed f...
متن کاملUtilization of C14 labeled pyruvate and acetate by yeast.
The metabolism of pyruvate and acetate has been widely investigated in a variety of organisms. Studies of pyruvate fermentation in yeast, as well as the aerobic metabolism of both compounds in animals and microorganisms, have established the import.ance of decarboxylation as an initial step in the anaerobic metabolism of pyruvate and of the central position of the Krebs tricarboxylic acid cycle...
