Abstract
A propeptide converting enzyme capable of producing somatostatin-14 has been identified and partially characterized from anglerfish pancreatic islets. Results from N-terminal protein sequence analysis indicate that this enzyme is a member of the kex2/furin/PC family. This observation provides strong corroborative evidence that the kex2/furin/PC protease family is involved in propeptide conversion. Comparison of the obtained protein sequence with the cDNA sequence of mammalian PC2 also suggests that the active enzyme is derived from a precursor by cleavage at a site containing four consecutive basic amino acids.
