438603 |
1.14.17.1 | acetate |
the enzyme is inactive inactive in absence of activating anion at pH 5.1-5.3, high catalytic activity in presence of 0.2 M acetate buffer |
657814 |
1.14.17.1 | ascorbic acid |
complete dependance on added ascorbate, e.g. isoascorbate, glucoascorbate, D-ascorbate |
438607 |
1.14.17.1 | cAMP |
non-hydrolysable cAMP analog stimulates DBH promoter activity |
702956 |
1.14.17.1 | Cl- |
the enzyme is inactive inactive in absence of activating anion at pH 5.1-5.3, high catalytic activity in presence of 0.05-0.6 M Cl- in 50 mM Mes buffer. 0.6 M Cl- increases the optimum concentration of ferrocyanide from 0.25 mM to 2 mM |

1.14.17.1 | cytochrome b561 |
in ascorbate-loaded vesicle membranes can supply electron equivalents to support extravesicular dopamine beta-hydroxylase activity without the addition of any mediator, this activity is enhanced significantly by the addition of ferricyanide |
