Cell surface display of organophosphorus hydrolase using ice nucleation protein.
A new anchor system based on the ice nucleation protein (InaV) from Pseudomonas syringae INA5 was developed for cell surface display of functional organophosphorus hydrolase (OPH). The activity and stability of cells expressing the truncated InaV (INPNC)-OPH fusions were compared to cells with surface-expressed OPH using two other fusion anchors based on Lpp-OmpA and the truncated InaK protein....
متن کاملEvaluation of the organophosphorus hydrolase enzyme activity in creams and investigation of its stability
The main purpose of this project is investigation of the organophosphorus hydrolase (OPH) enzyme activity in water in oil (w/o) and oil in water (o/w) creams and investigation of the OPH enzyme stability in formulated creams. OPH enzyme was extracted and purified from strain flavobacterium. The w/o and o/w creams were prepared using different formulations. In order to achieve an emulsion with m...
متن کاملSurface display of organophosphorus hydrolase on Saccharomyces cerevisiae.
The gene encoding organophosphorus hydrolase (OPH) from Flavobacterium species was expressed on the cell surface of Saccharomyces cerevisiae MT8-1 using a glycosylphosphatidylinositol (GPI) anchor linked to the C-terminal region of OPH. Immunofluorescence microscopy confirmed the localization of OPH on the cell surface, and fluorescence intensity measurement of cells revealed that 1.4 x 10(4) m...
متن کاملConstruction of yeast strains with high cell surface lipase activity by using novel display systems based on the Flo1p flocculation functional domain.
We constructed a novel cell-surface display system, using as a new type of cell-wall anchor 3,297 or 4,341 bp of the 3' region of the FLO1 gene (FS or FL gene, respectively), which encodes the flocculation functional domain of Flo1p. In this system, the N terminus of the target protein was fused to the FS or FL protein and the fusion proteins were expressed under the control of the inducible pr...
متن کاملImproved degradation of organophosphorus nerve agents and p-nitrophenol by Pseudomonas putida JS444 with surface-expressed organophosphorus hydrolase.
Pseudomonas putida JS444, isolated from p-nitrophenol (PNP) contaminated waste sites, was genetically engineered to simultaneously degrade organophosphorus pesticides (OP) and PNP. A surface anchor system derived from the ice-nucleation protein (INP) from Pseudomonas syringae was used to target the organophosphorus hydrolase (OPH) onto the surface of Pseudomonas putida JS444, reducing the poten...
