rhamnogalacturonan I + H2O
rhamnogalacturonan I oligosaccharides with beta-D-galacturonic acid at the reducing end and L-rhamnopyranose at the nonreducing end
dearabinosylated and partially degalactosylated saponified modified hairy regions of apple pectin. Rhamnogalacturonan hydrolase also acts with inversion of anomeric configuration during hydrolysis of alpha-D-GalpA-(1->2)-alpha-L-Rhap linkages in rhamnogalacturonan, initially releasing oligosaccharides with beta-D-GalpA at the reducing end

rhamnogalacturonan I + H2O

rhamnogalacturonan I + H2O
rhamnogalacturonan I oligosaccharides with D-galacturonic acid at the reducing end and L-rhamnopyranose at the nonreducing end
the enzyme is able to cleave rhamnogalacturonan oligomers which contain 5 rhamnose units or more (i.e. degree of polymerization 9) with a rhamnose unit at both nonreducing and reducing end. Its preferential cleavage site is at four units from the first nonreducing rhamnose. In hairy regions of pectin the rhamnogalacturonan stretches have to be at least 13 residues long for rhamnogalacturonan hydrolase to produce one tetramer

RGI endo-hydrolases, RGHs, attack the RGI backbone randomly in an endo-fashion and catalyse bond cleavage of alpha-(1->2) glycosidic bonds between D-GalpA and L-Rhap. The mechanism involves an inversion of the anomeric C1 configuration in galacturonic acid releasing oligosaccharides with beta-D-GalpA at the reducing end and L-Rhap at the non-reducing end as products
