The major translation product of rat gastric mucosa RNA in a wheat germ cell-free system was identified as prepepsinogen by electrophoretic analysis of its immuno-precipitate on sodium dodecyl sulfate (SDS)-polyacrylamide gels and amino-terminal sequence determination. The translation product containing radioactive amino acids, purified by SDS-polyacrylamide gel electrophoresis, was shown to have an amino-terminal extension peptide comprising 16 amino acid residues. A partial amino acid sequence of this extension peptide is as follows: Met-X-X-Met-Val-Val-X-Leu-Leu-X-Leu-X-Leu-Leu-X-X-pepsinogen.
