ENZYMES SUITABLE FOR PEROXY ACIDS PRODUCTION Russian patent published in 2018 - IPC C12P7/40 C12N9/18 C11D3/386 A61K8/64 A61L2/16 

FIELD: biotechnology.

SUBSTANCE: method for peroxy acid production includes reaction of esters of carboxylic acids and inorganic peroxide in the presence of a polypeptide possessing with perhydroliticactivity and having an amino acid sequence, with at least 90% identity in relation to the amino acid sequence SEQ ID NO:4, provided that the amino acid residue associated with the C-terminal part of the catalytic histidine is not glutamic acid. The specified polypeptide is used to create a system for peroxycarboxylic acid production and delivery, a composition for personal hygiene, a composition for linen care and in a personal hygiene means. Also, an isolated polypeptide possessing perhydrolitic activity, containing the amino acid sequence of SEQ ID NO:14 or in SEQ ID NO:16, and its coding nucleic acid are proposed.

EFFECT: improved enzyme properties.
