  • PRODUCTION OF MONATIN ENANTIOMERS
    Publication number: 20110300282
    Abstract: Methods for preferentially hydrolyzing one stereoisomer of an isoxazoline diester over another, as well as an enzyme for facilitating the preferential hydrolysis are provided. Also provided are methods for providing mixtures of (RR) and (RS) monatin as well as (SS) and (SR) monatin, which methods can include the step of stereoselectively hydrolyzing an isoxazoline diester.
