iNAP-BrkA

iNAP is fused at C-terminal with BrkA anchoring protein. We use BBa_K880005 to construct the expression system and anchor iNAP on the surface of E.coli.


Biology

        BrkA is an anchor protein from Bordetella pertussis having β-barrel structure. It can anchor its passenger protein to the cell membrane and has been widely used in cell-surface display. iNap is a chimera of circularly permuted YFP (cpYFP) and the NADP(H) binding domain of Rex from Thermus aquaticus (T-Rex). Upon NADPH binding, iNap shows apparent fluorescence changes. iNap is fused at C terminal with BrkA so that iNap can be displayed on the surface of E. coli.[1][2]

Usage

        Here, we used BBa_K880005 to construct the expression system and obtained the composite part BBa_K3332050, which may achieve surface display of iNap on our engineering bacteria. Due to the limited time, we did not get the gene in time. As a result, there is a lack of data about this part. The progress of this part remains in the stage of design.
