  • Process for the modification of alkanes, fatty acids and fatty alcohols
    Patent number: 10975360
    Abstract: The present invention relates to a process for the microbial in-chain hydroxylation of C12 to C16 fatty acids, alcohols and alkanes at position ?-7, the process including the use of a microorganism expressing a cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity in the production of a hydroxylated product or secondary product. The present invention further relates to a process for the preparation of lactones, esters and polymers by hydroxylation of the corresponding fatty acids, fatty alcohols and alkane precursors by a recombinant cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity.

  • ONE STEP ENZYMATIC PROCESS FOR PRODUCING ALKYL FURANOSIDES
    Publication number: 20150125888
    Abstract: A process for enzymatically converting a furanoside substrate in a product of interest, includes contacting the substrate with an enzyme in presence of an alcohol acceptor, wherein the enzyme is preferably Araf51, and wherein the product is preferably an alkyl furanoside. The mutant Araf51 enzyme showing improved transglycosylation activity in comparison with the native wild-type (wt) Araf51 enzyme, and a method for screening the mutants are also described.
