carbon-oxygen lyase activity, acting on polysaccharides pectate lyase activity https://github.com/geneontology/go-ontology/issues/30193 EC:4.2.2.2 endogalacturonate transeliminase activity Catalysis of the reaction: a pectate = a pectate + a pectate oligosaccharide with 4-(4-deoxy-alpha-D-galact-4-enuronosyl)-D-galacturonate end. This reaction is the eliminative cleavage of pectate to give oligosaccharides with 4-deoxy-alpha-D-gluc-4-enuronosyl groups at their non-reducing ends. pectin trans-eliminase activity molecular_function PPase-N activity pectic acid lyase activity pectic lyase activity GO:0030570 polygalacturonic acid lyase activity alpha-1,4-D-endopolygalacturonic acid lyase activity polygalacturonic acid trans-eliminase activity polygalacturonate lyase activity MetaCyc:4.2.2.2-RXN pectic acid transeliminase activity polygalacturonic transeliminase activity (1->4)-alpha-D-galacturonan lyase activity PGA lyase activity endopectin methyltranseliminase activity endo-alpha-1,4-polygalacturonic acid lyase activity pectate transeliminase activity
