title: Ontogeny of peptidylglycine alpha-amidating monooxygenase activity in rapidly mineralizing bone from neonatal mouse.
abstract: Peptidylglycine alpha-amidating monooxygenase is hormonally, developmentally, and nutritionally regulated. In several tissues concomitant changes in enzyme activity and the level of expression of a known amidated peptide have been demonstrated. We report that neonatal mouse calvarium, a rapidly mineralizing bone, has detectable amidation enzyme activity. The level of activity varied 3-10-fold during the first 9 d of life. Production of one or more amidated peptides by bone may be coordinately regulated.
