pectate lyase L (polysaccharide lyase 9 family)
M-CSA #184
Endo-acting pectate lyase L (Pel9A) is from the bacteria Erwini chrysanthemi. It catalyses the eliminative cleavage of pectate to give oligosaccharides with 4-deoxy-alpha-D-gluc-4-enuronosyl groups at their non-reducing ends. This particular bacteria causes soft rot diseases. It secretes enzymes such as Pel9A which break down pectin, a key component of cell walls.
