Diadenylate cyclase

Gene

dacA

Organism
Listeria monocytogenes serovar 1/2a (strain ATCC BAA-679 / EGD-e)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the condensation of 2 ATP molecules into cyclic di-AMP (c-di-AMP) (PubMed:25605729). c-di-AMP is a signaling compound secreted into the host's cytosol where it triggers the cytosolic surveillance pathway (CSP), a host pathway of innate immunity characterized by expression of beta interferon (IFN-beta) and coregulated genes (PubMed:20508090). Expression of truncated proteins (missing first 80 or 100 residues) in E.coli leads to c-di-AMP synthesis (PubMed:25605729).2 Publications
