Part:BBa_K427001

C protein of the Mu bacteriophage

C is a protein of the Mu bacteriophage. It is typically transcribed by the middle promoter of the phage (Pm) and it activates the four late promoters Plys, Pi, Pp and Pmom. Since it is the activator of the late it can be used alongside them to build a sensitivity tuner that increases the POPS output of a construct. The part includes the ribosome binding site, so it can be used directly after a promoter in a genetic construct.

Usage and Biology

According to Kumaraswami (2004) two domains can be observed on the protein a Helix-Turn-Helix (HTH) domain and a dimerization domain, which suggests that the protein can only activate the promoters when in dimers.

This part has no special safety considerations.
