Gene coding for Ara h 2

Gene coding for the peanut allergen Ara h 2

Introduction

This part is composed of the gene coding for the allergen of peanut Ara h 2 (NCBI: AY158467.1). The peanut allergy prevalence is higher than 5% (Lieberman and al. 2018) in developped countries and Ara h 2, among the 17 other peanut allergens, triggers 90% of the peanut allergies (Lehmann and al. 2003). Ara h 2 have already been expressed in E. coli and was able to bind the IgE of patient with peanut's allergie (Lehmann and al. 2003).

Construction

The objective of the INSA-UPS 2022 team was to display Ara h 2 on the surface of E. coli so the ordered sequence was merged to OmpA membrane lipoprotein (see part BBa_K1694008).
