- PubMed Abstract:
Pectic substances are the major polysaccharide components of the middle lamella and primary cell wall of dicotyledonous plants. They consist of homogalacturonan 'smooth' regions and highly rhamnified 'hairy' regions of rhamnogalacturonan. The backbone in rhamnogalacturonan-l (RG-l), which is composed of alternating galacturonic acid and rhamnose residues, is the substrate for a new class of enzymes known as rhamnogalacturnoases (RGases). RGase A is a novel enzyme implicated in the enzymatic degradation of RG-l.
