Abstract
PURPOSE: To prepare L-5-hydroxytryptophane industrially inexpensively by an enzymatic action, by using 5-hydroxyindole and DL-serine or D-serine as raw materials.
CONSTITUTION: 5-Hydroxyindole and DL-serine or D-serine as raw materials are treated with tryptophane synthetase or tryptophanase and an enzyme to racemize serine and the reaction is carried out while D-serine is partially converted into L-serine.
