Pmom promoter of Mu bacteriophage

Pmom is one of the four late promoters of the Mu bacteriophage. It can be activated by the C protein, which is produced by the middle promoter Pm. Pmom works because of a special configuration of the DNA. It can be used to create a sensitivity tuner alongside the C protein of the same phage. This construction can be used to increase the POPS output of a promoter.

Usage and Biology

The activation of the promoter requires the holenzyme σ70, which normally binds to the -35 and -10 consensus sequences, the promoter has the -10 but does not have the -35 sequences instead it has another sequence approximately at -51 where the activator protein binds. Once the protein is located there, the holenzyme σ70 recognizes the promoter and transcription begins.

This part has no special safety considerations.
