Hpall promoter

The PHpaII promoter1, is a strong constitutive promoter that is commonly used for expression in gram-positive bacteria. Since the promoter is not mapped, the sequence includes the 5'UTR, as well as the RBS.

Usage and Biology

The promoter has better affinity to the binding site of RNA polymerase or other transcription activators which help in increasing the transcription rate of downstream DNA to messenger RNA2,3,4. The PHpaII promoter stimulates counterclockwise RNA synthesis5. Comparable expression strength to that of P432. In our case it was used to produce high amounts of heterologous protein (BBa_K2924033, BBa_K2924052) that is secreted into the culture supernatant.
