Ramnogalakturonanska ramnohidrolaza (EC 3.2.1.174, RG-ramnohidrolaza, RG alfa-L-ramnopiranohidrolaza) je enzim sa sistematskim imenom ramnogalakturonan oligosaharid alfa-L-Rha-(1->4)-alfa-D-GalA ramnohidrolaza.^[1]^[2] Ovaj enzim katalizuje sledeću hemijsku reakciju

eksohidroliza alfa-L-Rha-(1->4)-alfa-D-GalA veze u ramnogalakturonanskim oligosaharidima sa inicijalnom inverzijom konfiguracije čime se oslobađa beta-L-ramnoza sa neredukujućeg kraja ramnogalakturonanskih oligosaharida

Ovaj enzim učestvuje u degradaciji ramnogalakturonana I kod Aspergillus aculeatus.
