Expression of receptor binding protein (gp37) on the outer membrane of Escherichia coli with RFP
Contains the elements necessary to recognize and bind an Escherichia coli bacteria.The major component is the gene product (gp) 37 which codes for the T4 bacteriophage recpetor binding protein (RBP) conferring the ability to recongize another target bacteria (E.coli in this case). Gp37 will be directed to the outer membrane of our model organism, E. coli K12. This will be achieved thanks to the co-expressed Lpp-OmpA gene. The Lpp-OmpA is an existing part designed by the NCTU-Formosa team in 2015 (Part: BBa_K1694002). It consists of a N-terminal acids of the lipoprotein (Lpp) sequence followed by amino acids of outer membrane protein A (OmpA). By fusing gp37 to the C-ter end of Lpp-OmpA, it can be displayed on the outer membrane of E. coli. Between the Lpp-OmpA and the gp37, is a red fluorescent marker (RFP) allowing to localize the LTF in the chassis. This BioBrick also contains a cleavage site, the TEV cleavage site, which is a unique cleavage site of the cysteine protease from the Tobacco Etch Virus (TEV). This cleavage site is followed by a His-tag in case of a purification step which can be performed with Ni2+ chromatography columns.
Two chaperones proteins (gp38 and chaperone protein 57A) are present as well for the physical appearance of the gp37.
