1 Evidence for involvement of protein kinase in the activation by adenosine 3":5"-monophosphate of brain tyrosine 3-monooxygenase. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
2 Addition of adenosine 3":5"-monophosphate (cAMP) to high speed supernatant preparations obtained from rat brain caused a 3- to 4-fold increase in tyrosine 3-monooxygenase (tyrosine hydroxylase) activity. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
3 Addition of adenosine 3":5"-monophosphate (cAMP) to high speed supernatant preparations obtained from rat brain caused a 3- to 4-fold increase in tyrosine 3-monooxygenase (tyrosine hydroxylase) activity. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
4 Addition of adenosine 3":5"-monophosphate (cAMP) to high speed supernatant preparations obtained from rat brain caused a 3- to 4-fold increase in tyrosine 3-monooxygenase (tyrosine hydroxylase) activity. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
5 Addition of adenosine 3":5"-monophosphate (cAMP) to high speed supernatant preparations obtained from rat brain caused a 3- to 4-fold increase in tyrosine 3-monooxygenase (tyrosine hydroxylase) activity. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
6 The tyrosine 3-monooxygenase remained in an activated state upon removal of the cAMP by passing the enzyme through a Sephadex G-25 column. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
7 Substances which inhibit cAMP-dependent protein kinase, namely, EDTA, ADP, and adenosine, and protein kinase modulator, each antagonized the activation of tyrosine 3-monooxygenase produced by cAMP. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
8 The activation of tyrosine 3-monooxygenase by added cAMP and protein kinase required the presence of ATP and Mg-2+. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
9 These data suggests that the cAMP activation of tyrosine 3-monooxygenase may be mediated by a cAMP-dependent protein kinase. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
10 These data suggests that the cAMP activation of tyrosine 3-monooxygenase may be mediated by a cAMP-dependent protein kinase. Cyclic AMP tyrosine hydroxylase Rattus norvegicus
