Involved in degradation of plant cell walls. Hydrolyzes the feruloyl-arabinose ester bond in arabinoxylans, and the feruloyl-galactose ester bond in pectin. Active against paranitrophenyl-acetate, methyl ferulate and wheat arabinoxylan. feruloyl-polysaccharide + H2O = ferulate + polysaccharide. Optimum pH is 6.1. Optimum temperature is 37 degrees Celsius. Induced during growth on suberin. Belongs to the faeC family.
