CC -!- FUNCTION: Participates in a DNA-damage check-point that is active prior
CC to asymmetric division when DNA is damaged. DisA forms globular foci
CC that rapidly scan along the chromosomes during sporulation, searching
CC for lesions. When a lesion is present, DisA pauses at the lesion site.
CC This triggers a cellular response that culminates in a temporary block
CC in sporulation initiation. {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 acts as a signaling molecule that couples DNA integrity with
CC progression of sporulation. The rise in c-di-AMP level generated by
CC DisA while scanning the chromosome, operates as a positive signal that
CC advances sporulation; upon encountering a lesion, the DisA focus
CC arrests at the damaged site and halts c-di-AMP synthesis.
CC {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 -!- ACTIVITY REGULATION: Diadenylate cyclase activity is inhibited by the
CC interaction with RadA. {ECO:0000250}.
CC -!- SUBUNIT: Homooctamer (By similarity). Interacts with RadA.
CC {ECO:0000255|HAMAP-Rule:MF_01438, ECO:0000269|PubMed:23760274}.
CC -!- SIMILARITY: Belongs to the DisA family. {ECO:0000255|HAMAP-
CC Rule:MF_01438}.
