Rhamnogalacturonan galacturonohydrolase

Rhamnogalacturonan galacturonohydrolase (EC 3.2.1.173, RG-galacturonohydrolase) is an enzyme with systematic name rhamnogalacturonan oligosaccharide alpha-D-GalA-(1->2)-alpha-L-Rha galacturonohydrolase.[1] This enzyme catalyses the following chemical reaction

Exohydrolysis of the alpha-D-GalA-(1->2)-alpha-L-Rha bond in rhamnogalacturonan oligosaccharides with initial inversion of configuration releasing D-galacturonic acid from the non-reducing end of rhamnogalacturonan oligosaccharides.
