Biological Properties |

General Function: | negative regulation of DNA-dependent DNA replication initiation |
---|
Specific Function: | Mediates the interactions of DNA replication initiator protein DnaA with DNA polymerase subunit beta sliding clamp (dnaN). Stimulates hydrolysis of ATP-DnaA to ADP-DnaA, rendering DnaA inactive for reinitiation, a process called regulatory inhibition of DnaA or RIDA. ADP-binding activates Hda to hydrolyze DnaA-ATP; Hda monomers bind to ADP with about 200-fold greater affinity than for ATP. RIDA function can be genetically separated from viability, suggesting this protein has another function as well.Suppresses the toxic effect of overexpressing a TrfA N-terminal 163 residue fragment. Inhibits inner membrane-associated plasmid IncP-alpha RK2 replication probably by interacting with plasmid-encoded TrfA. |
