چکیده انگلیسی
Three genes respectively encoding d-specific hydantoinase (DHHase), N-carbamoyl-d-amino acid amidohydrolase (DCHase) and hydantoin racemase (HRase) were co-expressed in E. coli in a system designed for the efficient enzymatic production of d-amino acids via a combination of hydantoin hydrolysis and hydantoin racemization. With the use of whole cells, the d-forms of eight amino acids - d-phenylalanine, d-tyrosine, d-tryptophan, O-benzyl-d-serine, d-valine, d-norvaline, d-leucine and d-norleucine - were efficiently converted from the corresponding dl-5-monosubtituted hydantoin compounds.
