The Shape of Allergenic Proteins
A team of researchers has discovered that many of the plant proteins that cause allergies have similar shapes.
In order to find out the significance of shape, the researchers used computer modelling to look at the structure of 129 common food allergens. Then they classified the molecules by shape. It turned out that 129 allergens belonged to only 20 or 3849 possible protein "families" in the plant world, and 2/3 of allergens actually came from only 4 families.
