Lac/Ara-1 IPTG Inducible Promoter

Derived from the L-arabinose and Lactose operons, this synthetic promoter remains in the 'off' state due to the repression of the AraC protein. AraC is constitutively expressed in bacteria possessing the arabinose operon and as such is present in E. coli. When exogenous arabinose and/or IPTG is added, the AraC protein is freed from the promoter thus allowing RNA polymerase to bind and initiate transcription. Hence, addition of arabinose or IPTG will switch the promoter into the 'on' state.
