[Some structural properties of 80S acid protein from pea ribosomes].
The 80S acid protein from pea ribosomes similar to the L7/L12 protein from E. coli was studied. This protein was found to be rich in alanine (18 mol.%) and to contain an acid amino acids excess over basic ones, the ratio of basic amino acids to acid ones was 0.42. As in the case of other eukaryotic L7/L12 homologs studied, the N-terminal amino acid of the protein is methionine. Using the double immunodiffusion technique, no crossreaction of E. coli anti-L7/L12 with 80S acid protein from pea ribosomes was observed. It was assumed that the protein molecule contains conservative sites responsible for the specific functioning of eukaryotic L7/L12 homologs.
