Characterization of the sites phosphorylated on tyrosine hydroxylase by Ca 2+ and phospholipid-dependent protein kinase, calmodulin-dependent multiprotein kinase and cyclic AMP-dependent protein kinase

Tyrosine hydroxylase purified from rat pheochromocytoma is phosphorylated rapidly by the Ca 2+- and phospholipid-dependent protein kinase (protein kinase C) purified from rat or sheep brain. Phosphorylation was stimulated 14-fold by Ca 2+ and phosphatidylserine and occurred at a rate comparable with...

Description
Summary:Tyrosine hydroxylase purified from rat pheochromocytoma is phosphorylated rapidly by the Ca 2+- and phospholipid-dependent protein kinase (protein kinase C) purified from rat or sheep brain. Phosphorylation was stimulated 14-fold by Ca 2+ and phosphatidylserine and occurred at a rate comparable with that of the phosphorylation of histone H1. The phospholipid-dependent protein kinase phosphorylates a single site which is identical to that phosphorylated by cyclic AMP-dependent protein kinase and to the secondary site of phosphorylation by the calmodulin-dependent multiprotein kinase. The implications of these results with respect to the regulation of catecholamine biosynthesis in adrenal medulla are discussed.
