Introduction
Mmp1 is an inducible promoter that was designed and characterized by Zhao H (2017)[1] for Halomonas. T7 Promoters are promoters that work with T7 RNA Polymerase.The chromosome of Halomonas sp. TD we used already integrated the RNAP module of MmP1, which was under the control of a lacI-regulated Ptac promoter, named the TD-Mmp1 platform strain. Meanwhile, the promoter module of MmP1 was cloned into pSEVA321 to obtain a PT7-like-p321 plasmid, and then transferred into TD-Mmp1 through conjugation.
In order to reduce the leakage level of the Mmp1 promoter, one more lacO was introduced immediately after the transcription start site (+1) of PT7-like (producing PT7-like-LacO).The Mmp1 inducible promoter currently used by our team has undergone various optimizations as described above.
