A secretory granule associated enzymatic activity from the rat anterior pituitary that can convert the synthetic peptide D-Tyr-Val-Gly into D-Tyr-Val-NH2 is described. Due to the presence of inhibitory activity in the cytosol and rough endoplasmic …
Mouse anterior pituitary corticotropic tumor cells (AtT-20/D-16v) were homogenized and subjected to subcellular fractionation. A secretory granule associated enzyme activity was detected which could convert D-Tyr-Val-Gly into D-Tyr-Val-NH2. The …
An enzymatic activity capable of producing an alpha-amidated peptide product from its glycine-extended precursor has been identified in secretory granules of rat anterior, intermediate, and neural pituitary and bovine intermediate pituitary. High …
