• PubMed Abstract: 
  

  Structure-guided design of substrate-binding pocket inversed the stereoselectivity of an NADH-dependent medium-chain alcohol dehydrogenase (MDR) from Prelog to anti-Prelog. The pocket-forming amino acids, especially the unconserved residues as hotspots, play critical roles in directing MDRs' stereoselectivity.
