FERMENT FOR PRODUCTS OF LONG-CHAIN PEROXY ACID Russian patent published in 2013 - IPC C12N15/55 C12N1/11 C12N9/16 C12N9/52 C11D3/386 

FIELD: biotechnologies.

SUBSTANCE: peroxy hydrolase ferment is described, which may hydrolyze n-nitrophenylcaproate (pNC6) or n-nitrophenyloctanoate (pNC8) in presence of peroxide, where the specified ferment includes one of the following combinations of amino acid substitutes: Ala in the position 154 and Met in the position 194; Gly in the position 154 and Val in the position 194; or Gly in the position 12 and Met in the position 194, where the specified positions of amino acids are positionally equivalent to positions 12, 154 and 194 in the sequence SEQ ID NO: 2 of peroxy hydrolase M. smegmatis, and where the specified ferment produces peroxy acid. The following components are disclosed: produced nucleic acid, which codes the specified peroxy hydrolase ferment; recombinant nucleic acid, which expresses the peroxy hydrolase ferment, including a promotor and the specified produced nucleic acid; a vector of expression, including the specified recombinant nucleic acid; a host cell containing the recombinant nucleic acid and producing the peroxy hydrolase ferment. Compositions are described for washing, bleaching and disinfection, including effective amount of peroxy hydrolase ferment and source of hydrogen peroxide. Methods of washing, bleaching and disinfection are proposed, which include maintenance of a substrate in presence of the specified compositions for washing, bleaching or disinfection of the specified substrate, accordingly. Besides, it is suggested to use the specified produced peroxy hydrolase ferment for hydrolysis of an acyl ether substrate containing up to 8 atoms of carbon, in presence of hydrogen peroxide.

EFFECT: invention makes it possible to perform a reaction of hydrolysis of the specified compound in presence of hydrogen peroxide with formation of peroxy acids.
