Abstract:1. By incubation of Ehrlich ascites-carcinoma cells in vitro with [1-(14)C]glycine the relation between the uptake of glycine and its incorporation into protein was examined. 2. With dl-methionine as a competitive inhibitor, there was not only a decrease in uptake of this amino acid, but also inhibition of its incorporation into protein. 3. It is only in its initial stage that the increase in incorporation is accompanied by increase in intracellular concentration of free glycine. Further increase in the amino … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
