Pectinolytic enzymes consist of four classes of enzymes: pectine lyase, polygalacturonase, pectin methylesterase and rhamnogalacturonase. Hydrolyzes alpha-D-galacturonopyranosyl-(1,2)-alpha-L-rhamnopyranosyl linkages in the backbone of the hairy regions of pectins (By similarity). Belongs to the glycosyl hydrolase 28 family.
