Endo-polygalacturonase (EC 3.2.1.15, pectin depolymerase, pectolase, pectin hydrolase, and poly-α-1,4-galacturonide glycanohydrolase; systematic name (1→4)-α-D-galacturonan glycanohydrolase (endo-cleaving)) is an enzyme that hydrolyzes the α-1,4 glycosidic bonds between galacturonic acid residues: (1,4-α-D-galacturonosyl)n+m + H2O = (1,4-α-D-galacturonosyl)n + (1,4-α-D-galacturonosyl)m

rdfs:comment	La poligalacturonasa es una enzima hidrolasa (EC 3.2.1.15, CAS 9032-75-1 ), endo o exo, que inicia el corte hidrolítico por el extremo no reductor del polímero de pectina, su sustrato, especialmente la de bajo metoxilo. Se encuentra en algunas bacterias, hongos y levaduras, fundamentalmente fitopatógenos, y es de mucha aplicación en la industria del zumo.La poligalacturonasa se encuentra en los frutos de plantas como el tomate. La actividad de la poligalacturonasa se relaciona con la maduración de estos frutos ya que causa la rotura de la lámina media de las paredes celulares del tomate, provocando ablandamiento de los tejidos y cambios en la textura del fruto (es) Polygalacturonasen, auch bekannt als Pektin-Depolymerasen, PG, Pektolasen, Pektinhydrolasen und Poly-alpha-1,4-Galacturonid-Glycanohydrolase, sind pflanzliche Enzyme. Ihre Hauptfunktion ist die Hydrolyse (Spaltung unter Verwendung von Wasser) von alpha-1,4-glycosidischen Bindungen zwischen den Galacturonsäureeinheiten von Polygalacturonan, ein Bestandteil des Pektinnetzwerks von Pflanzenzellwänden. Durch diese Auflockerung der Zellwand trägt die Aktivität endogener Pflanzen-Polygalacturonasen dazu bei, dass Früchte während des Reifungsprozesses weicher und süßer werden. Auf ähnlicher Weise verwenden Phytopathogene Polygalacturonasen als Mittel zur Schwächung des Pektinnetzwerks von Pflanzen, so dass Verdauungsenzyme in den Pflanzenwirt ausgeschieden werden können, um Nährstoffe aufzunehmen (de) Endo-polygalacturonase (EC 3.2.1.15, pectin depolymerase, pectolase, pectin hydrolase, and poly-α-1,4-galacturonide glycanohydrolase; systematic name (1→4)-α-D-galacturonan glycanohydrolase (endo-cleaving)) is an enzyme that hydrolyzes the α-1,4 glycosidic bonds between galacturonic acid residues: (1,4-α-D-galacturonosyl)n+m + H2O = (1,4-α-D-galacturonosyl)n + (1,4-α-D-galacturonosyl)m (en) La poligalatturonasi è un enzima (numero EC 3.2.1.15) appartenente alla classe delle , che catalizza la seguente reazione di idrolisi: Acido poligalatturonico + H2O ⇄ Acido poligalatturonico (accorciato) + Acidi galatturonici (it)
