In previous studies we have demonstrated a secretory granule-associated peptide alpha-amidation activity in rat anterior, intermediate, and posterior pituitary. This activity is capable of converting 125I-labeled synthetic D-Tyr-Val-Gly to labeled …
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 …
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 …
