  • Method for the preparation of 2,4-dihydroxybutyrate
    Patent number: 11505811
    Abstract: A method for the preparation of 2,4-dihydroxybutyric acid from homoserine includes a first step of conversion of the primary amino group of homoserine to a carbonyl group to obtain 2-oxo-4-hydroxybutyrate, and a second step of reduction of the obtained 2-oxo-4-hydroxybutyrate (OHB) to 2,4-dihydroxybutyrate.
    Type: Grant
    Filed: January 13, 2020

  • Method of production of 2,4-dihydroxybutyric acid
    Patent number: 9890400
    Abstract: A method for the preparation of 2,4-dihydroxybutyric acid (2,4-DHB) including the successive steps of converting malate, succinyl-CoA and/or glyoxylate into malyl-CoA, converting malyl-CoA previously obtained into malate-4-semialdehyde, and converting malate-4-semialdehyde into 2,4-DHB using a DHB dehydrogenase.
