Involved in degradation of plant cell walls. Hydrolyzes the feruloyl-arabinose ester bond in arabinoxylans as well as the feruloyl-galactose and feruloyl-arabinose ester bonds in pectin (By similarity). Active against methyl esters of ferulate (MFA), sinapate (MSA), caffeate (MCA) and p-coumarate (MpCA) (PubMed:14595525). feruloyl-polysaccharide + H2O = ferulate + polysaccharide. Belongs to the serine esterase family.
