Usage and Biology
When ß-lactams bind to the PASTA domain of PknB, its kinase domain phosphorylates ATF2, which then binds to our promoter. The promoter was identified by (Miller et al., 2010) as cyclic AMP responsive element (Cre)-sequence. ATF2-binding site is a consensus: 5-GTGACGT[AC][AG]-3) cAMP response element (CRE) (Hai et al., 1989). Based on observations made by Miller and colleagues (2010) showing similar kinase mechanisms between the prokaryotic PknB and eukaryotic MAPK towards ATF2, we generated a synthetic ATF2-responsive promoter construct with three Cre and three AP1 binding sites as well as a miniCMV promoter sequence. ATF2 was identified as the best PknB interaction partner. As with all our constructs, our promoter is followed by a fluorescent marker gene miRFP670 to detect specific activation
Cloning
This plasmid was engineered with NEBBuilder HIFI assembly method. First the backbone GFP-C2neo was lineraized with AseI and BamHI, matching ends of gene and backbone ensured seamless cloning. We have designed this sequence threefold and condon-optimised to increase the signal intensity. To ensure a optimal gene expression of miRFP670 we clonded behind the recognition sequenz of ATF-1 a mini-CMV-Promotor.
