cyclic-di-AMP synthase; dacA (gene name); disA (gene name)
ATP:ATP adenylyltransferase (cyclizing)
Cyclic di-3′,5′-adenylate is a bioactive molecule produced by some bacteria and archaea, which may function as a secondary signalling molecule .
The intracellular bacterial pathogen Listeria monocytogenes secretes it into the host’s cytosol, where it triggers a cytosolic pathway of innate immunity .
