Reaction: Hydrolytic cleavage of 2-O-acetyl- or 3-O-acetyl groups of α-D-galacturonic acid in rhamnogalacturonan I.
Other name(s): RGAE
Systematic name: rhamnogalacturonan 2/3-O-acetyl-α-D-galacturonate O-acetylhydrolase
Comments: The degradation of rhamnogalacturonan by rhamnogalacturonases depends on the removal of the acetyl esters from the substrate [1].
