Name
rhamnogalacturonan galacturonohydrolase;
RG-galacturonohydrolase
Class
Hydrolases;

Sysname
rhamnogalacturonan oligosaccharide alpha-D-GalA-(1->2)-alpha-L-Rha galacturonohydrolase
Reaction(IUBMB)
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.
Comment
The enzyme is part of the degradation system for rhamnogalacturonan I in Aspergillus aculeatus.
