Tossup

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