[Enzymatic methyl esterification of the protein in bovine crystalline lens in culture].
In the present paper a study on the enzymatic methyl esterification of proteins in the bovine lens has been presented. The data obtained show that the synthesis of the methyl donor (AdoMet) as well as the methyl esterification of proteins are operative in the lens incubated in the presence of L-(methyl-14C) methionine and the amount of labelled methyl esters decreases during cell ageing. Furthermore, the Authors suggest the usefulness of this model system in the evaluation of the overall AdoMet metabolism in aging.
