Incorporation in vivo of methionine and ethionine into and the methylation and ethylation of rat liver nuclear proteins



Incorporation in vivo of methionine and ethionine into and the methylation and ethylation of rat liver nuclear proteins



Biochemical Journal 109(4): 697-699



Rats were given intraperitoneally methionine labelled with 35S or with 14C in the methyl group, or ethionine labelled with 35S or with 3H in the ethyl group and were killed 4 h later. Methionine was incorporated more readily than ethionine into all the nuclear proteins of liver. Lysine-rich histones incorporated more methionine and ethionine than arginine-rich histones and chromatin-associated acid protein also exceeded residual acid protein in this respect.
