  • Patent number: 11512330
    Abstract: It has been found that esterification of a hydroxy-fatty acid by a lipase can be coupled with oleate hydratase (OHase) generation of that hydroxy-FA from an unsaturated FA with a cis C9-C10 double bond, e.g. oleic acid, in a single aqueous buffered reaction medium at low temperature, e.g. 30° C. A simple one-pot enzymatic method to produce fatty acid estolides from one or more triglycerides, e.g. starting from a natural plant oil, is thereby enabled in which the same lipase catalyses both the initial hydrolysis of triglyceride and the final esterification step.
    Type: Grant

  • Publication number: 20120107870
    Abstract: The present invention relates to a process for the amidation of C-terminal esters or acids of peptide substrates in solution-phase synthesis of peptides, comprising amidating one or more peptide substrates comprising C-terminal esters or acids using the protease subtilisin in any suitable form in the presence of an ammonium salt derived from an acid having a pKa above 0. This process is useful in the production of protected or unprotected peptides.
