Part:BBa_K4197007
Ana o 3 expression at the surface of E. coli cells sortable by FACS using mRFP1
OmpA_ana o 3 fusion to display cashew allergen.
Introduction
This part is composed of the gene coding for the allergen of cashew Ana o 3 (NCBI: AAL91665.1). The cashew allergy prevalence is higher than 0.08% (Van der Valk and al. 2014) in the US countries and Ana o 3 binds specific antibodies of 100% of the patients with cashew allergy (Sato and al. 2019). Ana o 3 have already been expressed in E. coli and was able to bind the IgE of patient with cashew allergie (Robotham and al. 2005).Ana o 3 was merged to the membrane protein OmpA of E. coli (BBa_K1694002), to display Ana o 3 on the surface of E. coli . This lipoprotein is the most abundant in E. coli's membrane with 100,000 copies per cell (Ortiz-Suarez and al. 2016) and is often used to display protein on the surface of bacteria (Yang and al. 2016).
