ABSTRACT:
A process is disclosed for preparing phenylalanine which comprises contacting phenylpyruvic acid or phenylpyruvate with immobilized whole cells having transaminase activity in the presence of an amine donor. The cells are preferably immobilized with a polyazetidine polymer. Ruptured or permeabilized cells, with the enzyme in the free or immobilized state, may also be used. The preparation of phenylalanine from cinnamic acid using immobilized cells having phenylalanine ammonia lyase activity is also disclosed.
