ID 3.2.1.174 DE rhamnogalacturonan rhamnohydrolase. AN RG alpha-L-rhamnopyranohydrolase. AN RG-rhamnohydrolase. CA Exohydrolysis of the alpha-L-Rha-(1->4)-alpha-D-GalA bond in CA rhamnogalacturonan oligosaccharides with initial inversion of CA configuration releasing beta-L-rhamnose from the non-reducing end of CA rhamnogalacturonan oligosaccharides. CC -!- The enzyme is part of the degradation system for rhamnogalacturonan I CC in Aspergillus aculeatus. //
