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 |

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 |

RGI, degrading enzymes are active on the RGI backbone of pectin and are thus strictly specific for cleaving bonds in the repetitive [(1->2)-alpha-L-Rhap-(1->4)-alpha-D-GalpA-(1->2)] structure |
