these multiple components were not artifacts produced by limited proteolysis during purification of the enzyme , because the cell-free translation products in a reticulocyte lysate with poly ( a ) -mrna of rat liver consisted of multiple components of similar sizes , and because peptide mapping analyses with lysylendopeptidase and v8 protease demonstrated clear differences in the primary structures of these components .
