ABSTRACT:
A process is disclosed for catalyzing the transamination of an amino acid precursor to the corresponding L-amino acid by using aspartic acid as the amino donor and by adding certain multivalent metal ions, in the form of solid metal particles or pieces, to the system to catalyze the decomposition of oxalacetic acid, a by-product of the transamination.
