these results indicate that the proinsulin and proglucagon converting enzyme ( s ) in the anglerfish pancreatic islet is a unique intracellular thiol proteinase ( s ) that may be granule membrane-associated and may require the presence of prohormone sequences in addition to the dibasic residues at cleavage sites for substrate recognition and/or binding .
