CC -!- FUNCTION: Participates in a DNA-damage check-point. DisA forms globular
CC foci that rapidly scan along the chromosomes searching for lesions.
CC {ECO:0000255|HAMAP-Rule:MF_01438}.
CC -!- FUNCTION: Has also diadenylate cyclase activity, catalyzing the
CC condensation of 2 ATP molecules into cyclic di-AMP (c-di-AMP). c-di-AMP
CC likely acts as a signaling molecule that may couple DNA integrity with
CC a cellular process. {ECO:0000255|HAMAP-Rule:MF_01438}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 ATP = 3',3'-c-di-AMP + 2 diphosphate; Xref=Rhea:RHEA:35655,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:71500; EC=2.7.7.85;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01438};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01438};
CC -!- SUBUNIT: Homooctamer. {ECO:0000255|HAMAP-Rule:MF_01438}.
CC -!- SIMILARITY: Belongs to the DisA family. {ECO:0000255|HAMAP-
CC Rule:MF_01438}.
