RA Genoscope - CEA;
RL Submitted (APR-2012) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Plays an important role in the initiation and regulation of
CC chromosomal replication. Binds to the origin of replication; it binds
CC specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'-
CC TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids.
CC {ECO:0000256|HAMAP-Rule:MF_00377, ECO:0000256|RuleBase:RU000577}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|HAMAP-Rule:MF_00377}.
CC -!- SIMILARITY: Belongs to the DnaA family. {ECO:0000256|ARBA:ARBA00006583,
CC ECO:0000256|HAMAP-Rule:MF_00377, ECO:0000256|RuleBase:RU004227}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
