Ramnogalakturonanska galakturonohidrolaza (EC 3.2.1.173, RG-galakturonohidrolaza) je enzim sa sistematskim imenom ramnogalakturonan oligosaharid alfa-D-GalA-(1->2)-alfa-L-Rha galakturonohidrolaza.[1] Ovaj enzim katalizuje sledeću hemijsku reakciju
- eksohidroliza alfa-D-GalA-(1->2)-alfa-L-Rha veze u ramnogalakturonanskim oligosaharidima sa inicijalnom inverzijom konfiguracije čime se oslovađa D-galakturonska kiselina sa neredukujućeg kraja ramnogalakturonanskih oligosaharida
Ovaj enzim učestvuje u degradaciji ramnogalakturonana I kod Aspergillus aculeatus.
