Possible Interaction: Cysteine and Dihydroxyphenylalanine

Research Papers that Mention the Interaction

5-S-cysteinyl-DOPA and cysteine exhibit diminished I and phi-values relative to DOPA.
Pigment cell research  •  1987  |  View Paper
Reaction of dopa and cysteine catalysed by iron-EDTA complexes at physiological pH resulted in the formation of not only cystine but also conjugation products, cysteinyldopas among which 5-S-cysteinyldopa was the major product.
Biochemical pharmacology  •  1984  |  View Paper
Dopa concentrations decreased more rapidly in the presence of cysteine because cysteine addition to dopaquinone prevented reformation of dopa from dopaquinone.
When the concentration of cysteine decreased the cysteinyldopas were rapidly consumed and dopa concentrations increased sharply.
