WebbaraRencodes a LacI-type transcriptional regulator that negatively regulates the l-arabinose-inducible expression of araBDAand araE(encoding an l-arabinose transporter), through a mechanism that has yet to be identified. Here we show that the AraR protein binds in vitroto three sites: one upstream of araBDAand two upstream of araE. WebbArabinose gets eaten as food by bacteria so the induction concentrations are typically much higher than with IPTG. Arabinose induction is done at a 2-6 g/L final concentration, whereas IPTG induction is done at 0.12-0.24 g/L final concentration. There are advantages to using arabinose as well. Arabinose induction is titratable, meaning …
