>gnl|CDD|185744 cd09003, GH43_AXH_1, Glycosyl hydrolase family 43.  This glycosyl
           hydrolase family 43 (GH43) includes enzymes that have
           been characterized with beta-xylosidase (EC 3.2.1.37),
           alpha-L-arabinofuranosidase (EC 3.2.1.55), xylanase
           (endo-alpha-L-arabinanase) as well as arabinoxylan
           arabinofuranohydrolase (AXH) activities. These are all
           inverting enzymes (i.e. they invert the stereochemistry
           of the anomeric carbon atom of the substrate) that have
           an aspartate as the catalytic general base, a glutamate
           as the catalytic general acid and another aspartate that
           is responsible for pKa modulation and orienting the
           catalytic acid. Many of the enzymes in this family
           display both alpha-L-arabinofuranosidase and
           beta-D-xylosidase activity using aryl-glycosides as
           substrates. AXHs specifically hydrolyze the glycosidic
           bond between arabinofuranosyl substituents and
           xylopyranosyl backbone residues of arabinoxylan. Several
           of these enzymes also contain carbohydrate binding
           modules (CBMs) that bind cellulose or xylan. A common
           structural feature of GH43 enzymes is a 5-bladed
           beta-propeller domain that contains the catalytic acid
           and catalytic base. A long V-shaped groove, partially
           enclosed at one end, forms a single extended
           substrate-binding surface across the face of the
           propeller.
