Abstract
The preparation of L-2-amino-4-methylphosphinobutyric acid (L-PPT) by transamination of (3-carboxy-3-oxopropyl)-methylphosphinic acid with the aid of the L-PPT-specific transaminase from E. coli DH 1 is very much more efficient when the gene coding for this enzyme is isolated, incorporated into a plasmid and then a microorganism is transformed therewith.
