Three binding sites for AraC protein are required for autoregulation of araC in Escherichia coli .
As expected , expression of known AraC-regulated genes , i.e. , araB , araA , araD , araE , araF , araG , araH , and araJ , increased substantially upon addition of arabinose in wild-type cells and was substantially higher in wildtype cells than araC cells in the presence of arabinose ( Table 2 ) .
