A method for the synthesis of [14C]-kynurenine
Preparative Biochemistry
|January 1, 1984
Abstract:
A new method is described for the synthesis of [14C]-labelled L-kynurenine from [14C]-L-tryptophan, using extracts of tryptophan-adapted cells of Pseudomonas marginalis. It is based on the selective, rapid inactivation of kynureninase by a newly discovered inhibitor of this enzyme, 3-chloro-L-alanine. The yield of [14C]-kynurenine produced in this manner is 76% theoretical.
