Pectate lyase (EC 4.2.2.2) is an enzyme involved in the maceration and soft rotting of plant tissue.
[1] This enzyme catalyzes the chemical reaction The structure and the folding kinetics of one member of this family, pectate lyase C (pelC)1 from Erwinia chrysanthemi has been investigated in some detail,.
The folding mechanism of PelC involves two slow phases that have been attributed to proline isomerization.
Allergies are hypersensitivity reactions of the immune system to specific substances called allergens (such as pollen, synthetic materials, dust, stings, drugs, or food) that, in most people, result in no symptoms.
[5] Members of the Amb a I/a II family include Tobacco (Nicotiana tabacum, Common tobacco) pectate lyase, which is similar to the deduced amino acid sequences of two pollen-specific pectate lyase genes identified in Lycopersicon esculentum (Tomato);[6] Cry j I, a major allergenic glycoprotein of Cryptomeria japonica (Japanese cedar)—the most common pollen allergen in Japan;[7] and P56 and P59, which share sequence similarity with pectate lyases of plant pathogenic bacteria.
