Short version of the Promoter PpenP found in B. subtilis

This Promoter is a part used in the Beta-Lactam Biosensor project of [http://2017.igem.org/Team:TU_Dresden iGEM Team TU Dresden 2017 (EncaBcillus - It's a trap!)]. it controls the gene expression of the penP gene that codes for a beta-lactamase found in Bacillus subtilise. Yet there is not much known about the activity and activation of the beta-lactamase PenP in B. subtilis. The highest expression levels seem to be achieved when high salt concentrations occur. [http://www.subtiwiki.uni-goettingen.de/v3/gene/view/713BAB7190E1F86C55103049B29072F00E0DFFB3] PenP belongs to the class of Hydrolases and is able to break down beta-lactam antibiotics. The enzyme PenP harbours a signal peptide sequence and is most likely secreted and localized outside of the cell. [http://www.uniprot.org/uniprot/P39824] To investigate the influence that the presence of the beta-lactamase PenP in B.subtilis has on the sensitivity our biosensor, we analyzed the promoter activity of PpenP under antibiotic stress conditions.

This part features the RFC10 prefix and suffix:

Prefix with EcoRI, NotI, XbaI GAATTCGCGGCCGCTTCTAGA
Suffix with SpeI, NotI and PstI ACTAGTAGCGGCCGCTGCAGA

Sites of restriction enzymes generating compatible overhangs are indicated by sharing one color. (EcoRI and PstI are marked in blue, NotI in green, XbaI and SpeI in red)

Beta-Lactam Biosensor

In this subproject, we developed a functional and complete heterologous beta-lactam biosensor in Bacillus subtilis. By the time these specified cells sense a compound of the beta-lactam family, they will respond by producing a measurable luminescence signal. We further investigated the detection spectrum of the biosensor by testing different beta-lactam antibiotics from various subclasses. For increased control and easy handling of the biosensor strain during a potential field application, we demonstrate that the encapsulation of the cells into Peptidosomes is quite advantageous.
