. "Any process in which the symbiont modulates the frequency, rate or extent of the host adenylate cyclase activity, which involves catalysis of the reaction: ATP = 3',5'-cyclic AMP + diphosphate. The host is defined as the larger of the organisms involved in a symbiotic interaction." . . . "modulation by symbiont of host adenylate cyclase activity" .
