label_lc: endo-xylogalacturonan hydrolase activity
description: "Catalysis of the endohydrolysis of xylogalacturonate by cleavage of the alpha-(1,4)-linkage. Xylogalacturonate (XGA) is composed of a chain of alpha-(1,4)-linked D-galacturonic acid residues with beta-D-xylose substituted at the O3 position."
