Tyrosine Hydroxylase Is Inactivated by Catechol‐Quinones and Converted to a Redox‐Cycling Quinoprotein: Possible Relevance to Parkinson’s Disease

Abstract

Abstract Quinone derivatives of DOPA, dopamine, and N‐acetyldopamine inactivate tyrosine hydroxylase, the initial and rate‐limiting enzyme in the biosynthesis of the catecholamine neurotransmitters. The parent catechols are inert in this capacity. The effects of the catecholquinones on tyrosine hydroxylase are prevented by antioxidants and reducing reagents but not by scavengers of hydrogen peroxide, hydroxyl radicals, or superoxide radicals. Quinone modification of tyrosine hydroxylase modifies enzyme sulfhydryl groups and results in the formation of cysteinyl‐catechols within the enzyme. Catecholquinones convert tyrosine hydroxylase to a redox‐cycling quinoprotein. Quinotyrosine hydroxylase causes the reduction of the transition metals iron and copper and may therefore contribute to Fenton‐like reactions and oxidative stress in neurons. The discovery that a phenotypic marker for catecholamine neurons can be converted into a redox‐active species is highly relevant for neurodegenerative conditions such as Parkinson’s disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
