CC   -!- FUNCTION: Mediates the interaction of DNA replication initiator protein
CC       DnaA with DNA polymerase subunit beta sliding clamp (dnaN). Stimulates
CC       hydrolysis of ATP-DnaA to ADP-DnaA, rendering DnaA inactive for
CC       reinitiation, a process called regulatory inhibition of DnaA or RIDA
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: The active form seems to be an ADP-bound monomer. Forms the
CC       RIDA complex (regulatory inactivation of DnaA) of ATP-DnaA, ADP-Hda and
CC       the DNA-loaded beta sliding clamp (dnaN). {ECO:0000255|HAMAP-
CC       Rule:MF_01158}.
CC   -!- SIMILARITY: Belongs to the DnaA family. HdA subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01158}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAN44041.1; Type=Erroneous initiation; Evidence={ECO:0000305};
