the specificity of the ribosomal proteinase was studied using a variety of substrates : nascend peptides , ribosomal proteins , b-chain of insulin and some synthetic peptides ( the heptapeptide gly-phe-phe-tyr-thr-pro-lys ; the hexapeptide gly-phe-leu-gly-phe-leu and the cbz-hexapeptide ; the tripeptide phe-his-leu and the cbz-tripeptide ) .
