Methylated amino acids in the proteins of the cytoplasmic ribosome of Tetrahymena thermophila.
Two-dimensional electrophoretic analysis of proteins of the cytoplasmic ribosome of the protozoa Tetrahymena thermophila labeled in vivo with L-[14C1]methionine and L-[3H-methyl]methionine identifies one heavily methylated protein in each ribosomal subunit. These proteins, S31 and L21, each contain N epsilon-trimethyl-lysine.
