Photoactivated adenylyl cyclase
WebDec 1, 2016 · BLUF domain coupled photoactivated adenylyl cyclases (BLUF-PACs) are known to have elevated adenylyl cyclase activity upon blue light irradiation [20], [69]. The general function of BLUF-PAC in a cell is illustrated in Fig. 2. Blue light photo-activates the BLUF domain. It acts as the first cellular messenger. WebThe photoactivated adenylyl cyclase from Beggiatoa (bPAC) produces cAMP rapidly upon stimulation with blue light. However, light delivery is not always feasible, especially in vivo. Hence, we created a luminescence-activated cyclase by fusing bPAC with nanoluciferase (nLuc) to allow chemical activation of cAMP activity.
