Trypsin and disulfide bonds
WebAra h 3 (glycinin) is a cupin allergen belonging to the legumin family (6, 13). Legumins, also known as 11S globulins, are hexameric proteins present in the seeds of many plants (6). Subunits are synthesized as a single polypeptide which is cleaved to provide an acidic and a basic polypeptide chain, linked by a disulfide bond (6).
