Pectate lyases are enzymes from plants and plant pathogens involved in the maceration and soft rotting of plant tissue . They catalyze the eliminative cleavage of pectate, yielding oligosaccharides with 4-deoxy-α-D-mann-4-enuronosyl groups at their non-reducing ends. Pectate lyases are maximally expressed late in pollen development where they are involved in pectin degradation during pollen tube growth.
Two groups of allergens belong to this family. The group 1 Cupressaceae pollen allergens are major allergens identified in cedars, junipers, and cypresses . The major ragweed pollen allergens Amb a 1 and Amb a 2 show no IgE cross-reactivity to homologues from Cupressaceae . In addition, an IgE binding pectate lyase (Pen c 32) was identified in the mould Penicillium citrinum .
