abstract：:We used a morphological approach to determine the topogenic role of the signal peptide in mediating the ER translocation of yeast prepro-alpha-factor. In prepro-alpha-factor-somatostatin hybrids, changes in the N-terminal amino acid sequence from wild-type NH2-Met-Arg-Phe (MRF) to NH2-Met-Phe-Lys (MFK) caused a subtle...
