The existence of a glutamic acid racemase activity in Lactobacillus arabinosus has been reported by Narrod and Wood (1) and by Ayengar and Roberts (2). As has been pointed out by Meister (3) these observations with dried cell preparations would not exclude a mechanism for glutamic acid racemization in which alanine racemase is coupled with n-glutamic acid-nalanine transaminase and n-glutamic ac...

Free amino acids levels in the milk of 11 healthy Indian mothers were determined using automatic precolumn derivatization procedure. The aim of the study was to find out the relative concentration of glutamic acid and glutamine in the milk. Glutamic acid is the dominant free amino acid found in the milk of Indian mothers. Glutamic acid and glutamine together formed the major nonessential amino ...

Vender, Joyce (Indiana University, Bloomington), Kunthala Jayaraman, and H. V. Rickenberg. Metabolism of glutamic acid in a mutant of Escherichia coli. J. Bacteriol. 90:1304-1307. 1965.-A mutant strain of Escherichia coli W1485 was selected for its ability to utilize glutamic acid as the sole source of carbon. Growth of the mutant on glutamic acid led to the repression of glutamic acid dehydrog...

antibodies directed against the enzyme glutamic acid decarboxylase (gad) are believed to be the main cause of destruction of pancreatic islet cells in type i (insulin dependent) diabetes mellitus. the enzyme was found both in the brain and pancreatic beta cells. although similarities in identity of gad in human and rat brain have been demonstrated, little is known about the interaction between ...

The increasing prevalence of calcium pyrophosphate dihydrate (CPPD) deposition disease, a form arthritis with high inflammatory potential, has triggered considerable interest in the search for additives to prevent CPPD crystal formation, particularly field biomineralization. In this context, crystallization aqueous solution and without glycine, glutamic acid, or glycyl-L-glutamic acid as crysta...

Recently we reported studies of the absorption of glutamic acid and glutamine from the gut of the cat by analysis of the portal blood, and of the concentration changes of the two amino acids in the peripheral blood plasma after oral administration of glutamic acid to human subjects (3). In a further study of the fate of glutamic acid and glutamine in the animal body, the uptake of the two amino...

The oxidation of glutamic acid by avirulent strains of Brucella abortus is the most rapid respiratory process thus far studied in this species (Gerhardt et al., 1950a). Furthermore, glutamic acid will serve as the sole source of both carbon and nitrogen for all strains of B. abortus which have been tested (Gerhardt et al., 1950b). Glutamic acid is important in the synthesis of other amino acids...
