Directed evolution of lipase A from Bacillus subtilis for the preparation of enantiocomplementary sec-alcohols
Biocatalysts with tailor-made or controllable stereoselectivity are valuable and highly desired in the precision synthesis of chiral compounds. Most lipases display excellent (R)-enantioselectivity for various sec-alcohols. In order to reverse the inherent (R)-enantioselectivity of lipase A from Bac...
