    What's a GeneRIF?
    1. The structural homology between DiaA and HobA strongly supports their involvement in the replication process and these proteins could define a new structural family of replication regulators in bacteria.
      Title: Structural similarity between the DnaA-binding proteins HobA (HP1230) from Helicobacter pylori and DiaA from Escherichia coli.
    2. DiaA regulates initiation by a novel mechanism, in which DiaA tetramers most likely bind to multiple DnaA molecules and stimulate the assembly of specific ATP-DnaA-oriC complexes.
