NS = no structure found meeting the requirements. and refer to the lowest energy docking pose that meets the criteria for valid structure whose geometry is pro or , respectively. Literature values for the enantiomeric excess (ee (%)) were obtained as follows: *values are from [11], and †values are from [9]. Prelog column indicates if the enzyme followed prelog or antiprelog rule for the given substrate. The last column indicates if the model correctly predicted the experimental results.
