PnisA

Originated from Lactococcus lactis subsp. Lactis, PnisA is a member of the two-component regulatory system NisK/NisR involved in the regulation of the biosynthesis of lantibiotic nisin. PnisA functions as a promoter which is activated by phosphorylated NisR and enhance downstream gene expression in response to environmental nisin signals. We managed to involve PnisA sequence in plasmids for E.coli strain.
Functioned together with NisK(BBa_K4307007), NisR(BBa_K4307008), J23100 and EGFP, it forms composite part J23100-nisK-nisR+PnisA-EGFP(BBa_K4307045) to express fluorescence signal induced by nisin.
