The enzyme oligogalacturonide lyase (EC 4.2.2.6) catalyzes the chemical reaction

4-(4-deoxy-β-D-gluc-4-enuronosyl)-D-galacturonate 2 5-dehydro-4-deoxy-D-glucuronate

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is oligogalacturonide lyase. Other names in common use include oligogalacturonate lyase, unsaturated oligogalacturonate transeliminase, and OGTE. This enzyme participates in pentose and glucuronate interconversions.

Pectate lyase is an enzyme involved in the maceration and soft rotting of plant tissue. Pectate lyase is responsible for the eliminative cleavage of pectate, yielding oligosaccharides with 4-deoxy-α-D-mann-4-enuronosyl groups at their non-reducing ends. The protein is maximally expressed late in pollen development. It has been suggested that the pollen expression of pectate lyase genes might relate to a requirement for pectin degradation during pollen tube growth.
