ChainsEnzyme NameDescriptionCatalytic Residues
pectate lyase C (polysaccharide lyase 1 family)  M-CSA #896

Involved in maceration and soft-rotting of plant tissue. Pectate lyase catalyses the eliminative cleavage of pectate to give oligosaccharides with 4-deoxy-alpha-D-gluc-4-enuronosyl groups at their non-reducing ends.
