Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

open access: yesAdvanced Science, Volume 13, Issue 18, 27 March 2026.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.

Understanding protein–flavor interactions: Factors, characterization techniques, and the effect of processing

open access: yesFood Biomacromolecules, Volume 3, Issue 1, Page 47-70, March 2026.
Abstract The perception of flavor in a food system depends on its release from the protein matrix. Apart from hydrogen bonding, hydrophobic interactions and van der Waal's forces, the formation of covalent adducts between the flavor and protein highly impacts the release of flavor from the protein matrix.
