ABSTRACT:
Enzyme-catalyzed synthetic reactions having otherwise unfavorable equilibria are facilitated by recovery of polypeptides by electrodialysis. A process of preparing polypeptides is provided that can be operated continuously to produce high yields of enriched polypeptides without recourse to post-synthetic product manipulations heretofore employed that are expensive and present a risk of residual toxic by-products. The invention is applied to advantage in the preparation of alpha-L-aspartyl-L-phenylalanine lower alkyl esters.
