Substrate specificities

Carbohydrate Esterase Family 3 (https://www.cazy.org/CE3.html) is comprised entirely of de-O-acetylxylan esterases. Xylan is a plant cell-wall polysaccharide composed of β-1,4-linked xylose decorated with α-arabinofuranose and α-glucuronic acid substituents.

Authors may get an idea of what to put in each field from Curator Approved Glycoside Hydrolase Families. (TIP: Right click with your mouse and open this link in a new browser window...)
