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
ascorbic acid
complete dependance on added ascorbate, e.g. isoascorbate, glucoascorbate, D-ascorbate
cAMP
non-hydrolysable cAMP analog stimulates DBH promoter activity
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
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
dehydroascorbate
-
ferricyanide
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
phosphate
the enzyme is inactive inactive in absence of activating anion at pH 5.1-5.3, high catalytic activity in presence of 0.1 M phosphate buffer
