Patent ID: 7951566

Claim:
A process for producing a peroxycarboxylic acid comprising: a) providing a set of reaction components, said components comprising: 1) a substrate selected from the group consisting of: i) esters having the structure wherein R 1 =C1 to C7 straight chain or branched chain alkyl optionally substituted with an hydroxyl or a C1 to C4 alkoxy group and R 2 =C1 to C10 straight chain or branched chain alkyl, alkenyl, alkynyl, aryl, alkylaryl, alkylheteroaryl, heteroaryl, (CH 2 CH 2 —O) n H or(CH 2 CH(CH 3 )—O) n H and n=1 to 10; ii) glycerides having the structure wherein R 1 =C1 to C7 straight chain or branched chain alkyl optionally substituted with an hydroxyl or a C1 to C4 alkoxy group and R 3 and R 4 are individually H or R 1 C(O); and iii) acetylated saccharides selected from the group consisting of acetylated monosaccharides, acetylated disaccharides, and acetylated polysaccharides; 2) a source of peroxygen; and 3) an enzyme catalyst comprising an enzyme, wherein said enzyme has perhydrolase activity and comprises a signature motif that aligns with a reference sequence SEQ ID NO: 2 using CLUSTALW, said signature motif comprising: i) an RGQ motif at positions corresponding to positions 118-120 of SEQ ID NO:2; ii) a GXSQG motif at positions corresponding to positions 179-183 of SEQ ID NO:2; and iii) an HE motif at positions corresponding to positions 298-299 of SEQ ID NO:2; and b) combining said reaction components under suitable reaction conditions whereby a peroxycarboxylic acid is produced.
