Activating Compound

EC Number Activating Compound Comment Organism Structure
4.6.1.1 cAMP the stimulatory effect of cAMP on adenylyl cyclase activity is enhanced in the presence of 0.005 mM Ca2+ and decreased in the presence of 0.1 mM Ca2+ Tetrahymena pyriformis
4.6.1.1 D-glucose the stimulatory effect of D-glucose does not change in the presence of Ca2+ and calmodulin antagonists chloropromazine, N-(6-aminohexyl)-1-naphthalenesulfonamide hydrochloride, and N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide hydrochloride Tetrahymena pyriformis
4.6.1.1 EGF the stimulatory effect of EGF on adenylyl cyclase activity is enhanced in the presence of 0.005 mM Ca2+ and decreased in the presence of 0.1 mM Ca2+ Tetrahymena pyriformis
4.6.1.1 Insulin the stimulatory effect of insulin on adenylyl cyclase is decreased to 28% in the presence of 0.1 mM Ca2+ Tetrahymena pyriformis
4.6.1.1 serotonin the stimulatory effect of serotonin on adenylyl cyclase activity (253%) is enhanced in the presence of 0.005 mM Ca2+ Tetrahymena pyriformis

Inhibitors

EC Number Inhibitors Comment Organism Structure
4.6.1.1 Ca2+ at 0.1 mM and higher, the calcium cations inhibit the adenylyl cyclase activity Tetrahymena pyriformis

Metals/Ions

EC Number Metals/Ions Comment Organism Structure
4.6.1.1 Ca2+ maximum stimulatory effect at 0.002 mM Ca2+. (increase of 387% activity). Antagonists of calmodulin, N-(6-aminohexyl)-1-naphthalenesulfonamide hydrochloride and N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide hydrochloride, at concentrations of 0.02-0.1 mM decrease the stimulatory effect of 0.005 mM Ca2+, while at the higher concentrations inhibit it completely. Chloropromazine decreases the Ca2+-stimulated adenylyl cyclase activity only at concentrations of 0.2-1.0 mM Tetrahymena pyriformis
