Substrate specificities
GH43 enzymes display a variety of exo-activities in which L-arabinofuanose, D-galactopyranose and D-xylopyranose residues are hydrolyzed from the non-reducing end of polysacchrides or aryl groups. In addition examples of endo-alpha1,5-arabinanases are also evident in this family
