PERHYDROLASE PROVIDING IMPROVED PERACID STABILITY |
摘要 |
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 Thermotoga maritima acetyl xylan esterase gene was modified using error-prone PCR and site-directed mutagenesis to create an enzyme catalyst characterized by an increase in the ratio of peracetic acid formation to peracetic acid hydrolysis specific activities (PAAF/PAAH ratio). 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. |
