Biochem/physiol Actions

L-Meta-tyrosine is metabolite of L-Phenylalanine generated within the living organism by hydroxyl free radical. It is a marker of oxidative stress. Circulating L-Meta-tyrosine cold be incorporated into protein through the binding to the tRNAPhe. In plants L-Meta-tyrosine (m-Tyr) is also synthesized enzymatically and has been shown to act as a natural herbicide. It inhibits the growth of plants. L-Meta-tyrosine is a potent and selective competitive inhibitor of Enterobacteriaceae (Citrobacter, Proteus, Erwinia) tyrosine phenol-lyase that exhibits a renoprotective effect in diabetic mice. L-Meta-tyrosine decreases plasma phenyl sulfate and indoxyl sulfate levels and reduces albuminuria in diabetic mice models. Also, L-Meta-tyrosine inhibits bacterial tryptophan indole-lyase. It does not alter composition of microbiota in renal failure mice model.

L-Tyrosine (Tyr) is one of the twenty proteinogenic amino acids and also acts as a precursor for secondary metabolites. Tyr is prone to modifications, especially under conditions of cellular redox imbalance. The oxidation of Tyr precursor phenylalanine leads to the

A link between oxidative stress and insulin resistance has been suggested. Hydroxyl free radicals are known to be able to convert phenylalanine (Phe) into the non-physiological tyrosine isoforms ortho- and meta-tyrosine (o-Tyr, m-Tyr). The aim of our study was to
