| FUNCTION | Catalyzes the condensation of 2 ATP molecules into cyclic di- AMP (c-di-AMP), a second messenger used to regulate differing processes in different bacteria. |
| CATALYTIC ACTIVITY | Reaction=2 ATP = 3',3'-c-di-AMP + 2 diphosphate; Xref=Rhea:RHEA:35655, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:71500; EC=2.7.7.85; |
| SUBUNIT | Probably oligomerizes. |
