Function

CDAA_BACSU One of 3 paralogous diadenylate cyclases (DAC) in this bacteria, catalyzing the condensation of 2 ATP molecules into cyclic di-AMP (c-di-AMP) (Probable). Upon expression in E.coli leads to c-di-AMP synthesis (PubMed:23192352). Probably the main producer of c-di-AMP for the cell; is probably implicated in control of peptidogylcan synthesis (PubMed:22211522, PubMed:23192352, PubMed:26240071). In B.subtilis c-di-AMP is a second messenger that mediates growth, DNA repair and cell wall homeostasis; it is toxic when present in excess (PubMed:26240071).^[1] ^[2] ^[3]
