superfold GFP~PenP fusion construct for localization studies

This gene 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 codes for a beta-lactamase found in Bacillus subtilis. 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. This enzyme also harbours a n-terminal signal peptide sequence and is most likely secreted and therefore localized outside of the cell. [http://www.uniprot.org/uniprot/P39824] To investigate the native localization of penP in Bacillus subtilis we fused the penP gene to the genetic sequence coding for superfold GFP (sfGFP) [BBa_K2273021].

This part features the RFC25 prefix and suffix to enable further translational fusions or promoter insertions upstream of the construct:

Prefix with	EcoRI, NotI, XbaI, RBS, spacer sequence, Start Codon and NgoMIV	GAATTCGCGGCCGCTTCTAGAAGGAGGTGTCAAAATGGCCGGC
Suffix with	AgeI, Stop Codon, SpeI, NotI and PstI	ACCGGTTAAACTAGTAGCGGCCGCTGCAGA

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, AgeI and NgoMIV in orange)

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.
