Abstract
A new lambda PL/cItrp regulation system was constructed which places the lambda cI repressor gene under the control of the tryptophan promoter/operator. This system allows prophage and temperature independent gene expression of lambda promoter plasmids. Protein synthesis is induced by blocking the production of lambda cI represser molecules through the addition to the growth medium of inexpensive supplements rich in tryptophan. Two cItrp constructs were placed on F′–factors for easy transfer into any suitable E. coli strain. The system should be useful for large scale production in E. coli of enzymes or other low added–value proteins.
