Abstract:We observed that the lysosomal enzyme, dipeptidylaminopeptidase I (DAP-I) caused the release of trichloroacetic-acid-soluble radioactivity from rat 1251-insulin-like growth factor-I1 . This activity could be blocked by dipeptide inhibitors of DAP-I, and was enhanced by chloride. Treatment of unlabeled rat IGF-I1 with DAP-I converted approximately 50% of the IGF-I1 to a species with a slightly shorter elution time on reverse-phase HPLC, whereas treatment of human IGF-I1 caused complete conversion to the species… Show more
