Feruloyl esterase

Feruloyl esterase is the plant-cell-wall-hemicellulose-auxiliary enzyme. It hydrolyzes the 4-hydroxy-3-methoxycinnamoyl (feruloyl) group from esterified sugar (usually arabinose), releasing ferulate and free polysaccharide; p-nitrophenyl acetate and methyl ferulate are poorer substrates. It is secreted and helps xylanases and pectinases. Expected in Eukaryota and Bacteria.
