J23100-RBS-Lpp-OmpA-GRHPR-terminator

        We anchored GRHPR protein onto membranes through Lpp-OmpA to catalyze the reaction of reducing glyoxalic acid and consuming NADPH. We use BBa_K880005 to construct the expression system and anchor GRHPR 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 has been widely used in cell-surface display. GRHPR, a Glyoxylate reductase from human liver, can reduce glyoxylic acid when NADPH is used as cofactor. GRHPR is fused at N terminal with Lpp-OmpA so that GRHPR can be displayed on the surface of E. coli.[1][2]

Usage

        Here, we used BBa_K880005 to construct the expression system and demonstrate the effect of Lpp-OmpA-GRHPR on the surface of E. coli. We obtained the composite part BBa_K3332058. Due to the limited time, we didn’t 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.
