Extracellular chlorogenic acid esterase that releases caffeic acid from chlorogenic acid (CGA) contained in natural substrates such as apple marc and coffee pulp (PubMed:17630312). Shows no activity towards 5-O-p-coumaroyl quinic acid, another quinic ester derivative, and rosmarinic acid, another caffeic ester derivative (PubMed:17630312). chlorogenate + H2O = (E)-caffeate + H(+) + L-quinate Optimum pH is 6.0. Optimum temperature is 60 degrees Celsius. Belongs to the type-B carboxylesterase/lipase family.
