Extracellular chlorogenic acid esterase that displays a surprisingly broad substrate profile (Ref.1). The enzyme's unique properties may contribute to the specific environmental interaction between the pathogenic fungus and its host, Zea mays (Ref.1). Additionally, the release of caffeic, p-coumaric, and ferulic acids from agroindustrial by-products such as destarched wheat bran (DSWB) and coffee pulp (CP) renders this enzyme an attractive candidate for the generation of natural aroma precursors and antioxidants (Ref.1). chlorogenate + H2O = (E)-caffeate + H(+) + L-quinate Optimum pH is 7.5. Optimum temperature is 37 degrees Celsius. Monomer. Belongs to the type-B carboxylesterase/lipase family.
