Lpp-OmpA-iNAP

iNAP is fused at N-terminal with Lpp-OmpA anchoring protein. We use K880005 to construct the expression system and anchor iNAP on the surface of E.coli.


Biology

        Lpp-OmpA is an anchor protein from E. Coli, which can anchor its passenger protein to the cell membrane. It is constituted of 1-9 amino acids of Lpp and 46-159 amino acids of OmpA. It 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 N terminal with Lpp-OmpA so that iNap can be displayed on the surface of E. coli.[1][2]

Usage

        Here, we use BBa_K880005 to construct the expression system and obtain the composite part BBa_K3332048, which may achieve surface display of iNap on our engineered 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.
