Assays for measuring the activity of this compound based on BRET and FRET methods include CAMYEL and FlCRhR (10[1])(“flicker”). By forcing one enzyme to bind to calmodulin, (-5[1])a virulence factor (-5[1])produced by members of the genus Bordetella increases levels of this compound. (10[2])The enzyme that produces this compound can be stimulated using Forskolin, (10[1]-5[1])and is (10[1])activated by the A (10[1])subunit of (10[1])cholera toxin, (10[2])which increases intracellular (10[2])levels of this (10[1])compound by over 100-fold. (10[1])Low glucose levels cause this molecule to allosterically bind to CRP (-5[3])as part (-5[1])of a (-5[1])positive (10[1])regulation mechanism. (-5[1])Phosphodiesterases most commonly (-5[1])act on (10[1])this compound, which (10[1])is necessary for the activity of protein kinase (10[1])A. (10[2]-5[1])For 10 points, name this secondary (-5[1])messenger molecule (10[1]-5[1])made (10[1])from ATP (10[5]-5[1])by (10[1])adenylyl (10[1]-5[1])cyclase. (10[1])■END■ (10[13]0[11])
