IciA protein, a specific inhibitor of initiation of Escherichia coli chromosomal replication.


Specific binding of IciA protein to the 13-mers in the origin of a minichromosome (oriC) inhibits initiation of replication in vitro by blocking the opening of this region effected by the initiator DnaA protein (Hwang, D.S., and Kornberg, A.
