Abstract
Initiation of DNA synthesis at an origin of DNA replication involves complex protein–DNA interactions that are still poorly understood. Some of these interactions are highly specific and involve proteins (initiator proteins) thought to be essential for regulation of the initiation process because of their rate-limiting activity1. We show here that both qualitative and quantitative changes in one of these proteins have profound effects on protein–DNA interactions at an origin of DNA replication, and are sufficient to reduce to less than one-third the minimal sequence required for initiation. The general implications of these findings are discussed.
