It has been found that it is possible to isolate from E. coli DH-l a transaminase with the aid of which it is possible with great efficiency to prepare L-phosphinothricin and .gamma.-aminobutyric acid from the appropriate precursors by transferring the amino group from glutamate. The novel transaminase has a molecular weight of 25,000 to 100,000 Dalton, an isoelectric point at a pH between 3.5 and 5.5 and a substrate specificity towards L-phosphinothricin .gamma.-aminobutyric acid and glutamate as amino-group donor as well as the appropriate keto compounds as amino acceptor.
