2.8.2.1 adenosine 3',5'-bisphosphate - 724077 2.8.2.1 adenosine 3',5'-bisphosphate the beta-enzyme form shows a hyperbolic dependence on adenosine 3',5'-bisphosphate concentration, whereas the alpha-enzyme form is not stimulated 645665 2.8.2.1 Diamide i.e. 1,1'-azobis(N,N-dimethylformamide), diamide significantly increases the sulfation of 7-hydroxycoumarin at an optimal concentration of 0.005 mM 724830 2.8.2.1 EDTA 10 mM, stimulates isozymes A and B 645641 2.8.2.1 ferulic acid activation of M-PST 645686 2.8.2.1 gallic acid activation of P-PST and M-PST 645686 2.8.2.1 gentisic acid activation of P-PST and M-PST 645686 2.8.2.1 GSH increases activity 645642 2.8.2.1 m-coumaric acid activation of P-PST 645686 2.8.2.1 additional information - 645688 2.8.2.1 additional information 5-amino-2-(4-amino-3-fluorophenyl)-6,8-difluoro-7-methyl-4H-1-benzopyran-4-one induces the expression of SULT1A1 via the aryl hydrocarbon receptor, AhR, signaling pathway, mechanism, overview 672912 2.8.2.1 additional information aryl sulfotransferase IV, oxidation causes an increase in sulfation of 4-nitrophenol and a shift of pH-optimum at physiological pH 645672 2.8.2.1 additional information estradiol, in constant application, leads to increased SULT1A1 levels in the striatum of rats, correlation of estradiol and SULT1A1 levels, other brain regions like cortex, cerebellum, and hippocampus, are less sensitive 672845 2.8.2.1 additional information glucocorticoids and prednisolone induce SULT1A3 activity on dopamine 1.2-1.8fold, but not SULT1A1, no effect by dexamethasone in Hep-G2 cells on SULT1A3 activity on 4-nitrophenol 675751 2.8.2.1 additional information structural basis for activation, mechanism 645688 2.8.2.1 additional information when p-hydroxybenzoic acid is combined with each of the other phenolic acids, a synergistic effect with respect to the promotion of PST-P activity is obtained. A potential synergistic effect for the PST-P activity is found in the following combination: p-hydroxybenzoic acid + gallic acid + gentisic acid, p-hydroxybenzoic acid + gallic acid + m-coumaric acid, p-hydroxybenzoic acid + o-coumaric acid + p-coumaric acid, p-hydroxybenzoic acid + o-coumaric acid + m-coumaric acid, gallic acid + gentisic acid + p-coumaric acid, and gallic acid + o-coumaric acid + m-coumaric acid 661915 2.8.2.1 morpholinosydnonimine i.e. SIN-1, a peroxynitrite generator, activates SULT1A3 in vivo in Hep-G2 cells 671885 2.8.2.1 o-coumaric acid activation of P-PST 645686 2.8.2.1 p-coumaric acid activation of P-PST 645686 2.8.2.1 p-hydroxybenzoic acid activation of P-PST and M-PST 645686 2.8.2.1 tert-butyl hydroperoxide tert-butyl hydroperoxide significantly increases the sulfation of 7-hydroxycoumarin at an optimal concentration of 0.01 mM 724830
