- This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is (1->4)-alpha-D-galacturonan lyase. Other names in common use include polygalacturonic transeliminase, pectic acid transeliminase, polygalacturonate lyase, endopectin methyltranseliminase, pectate transeliminase, endogalacturonate transeliminase, pectic acid lyase, pectic lyase, alpha-1,4-D-endopolygalacturonic acid lyase, PGA lyase, PPase-N, endo-alpha-1,4-polygalacturonic acid lyase, polygalacturonic acid lyase, pectin trans-eliminase, and Polygalacturonic acid trans-eliminase. This enzyme participates in pentose and glucuronate interconversions.
