Abstract

In the nutsedge, Cyperus rotundus L., the oxidation of L-tyrosine follows steps similar to those reported for mammalian liver and Blattella conjuncta. The system is activated by α-keto-glutarate, L-ascorbic acid, glutathione, and pyridoxal phosphate. Folic acid markedly inhibits the reaction.
