The l-threonine aldolase from Leishmania major was engineered to improve its diastereoselectivity by considering the physico-chemical properties of the substrate access path, leading to significant enhancement in diastereomeric excess (de) value.
The l-threonine aldolase from Leishmania major was engineered to improve its diastereoselectivity by a CAST/ISM strategy, providing insights into the relationship between the physico-chemical properties of the substrate access path and diastereoselectivity. The steric hindrance, hydrophobic interaction and pi-pi interaction cooperated to improve the diastereoselectivity of the enzyme, with a diastereomeric excess (de) value reaching 96.3%(syn) from 26.8%(syn).
