Perhydrolase Variant Providing Improved Specific Activity In the Presence of Surfactant

Abstract

An acetyl xylan esterase variant having perhydrolytic activity is provided for producing peroxycarboxylic acids from carboxylic acid esters and a source of peroxygen. More specifically, a variant of the Thermotoga maritima C277T acetyl xylan esterase is provided having an improved specific activity when producing peroxycarboxylic acids in the presence of an anionic surfactant. The variant acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.
