Abstract
PURPOSE: To prepare L-tryptophan by treating indole and DL-serine or D-serine with tryptophan-synthetase or tryptophanase in the presence of enzyme capable of racemizing serine.
CONSTITUTION: L-Tryptophan is prepared from indole and DL-serine or D-serine by the enzymatic action of tryptophan-synthetase or tryptophanase, in the presence of enzyme capable of racemizing serine, thereby converting at least a part of D- serine into DL-serine.
