Increases in S-nitrosylation and inactivation of the neuroprotective ubiquitin E3 ligase, parkin, in the brains of patients with Parkinson’s Disease (PD) are thought to be pathogenic and suggest a possible mechanism linking parkin to sporadic PD. Here we demonstrate that physiologic modification of parkin by hydrogen sulfide (H2S), termed sulfhydration, enhances its catalytic activity. Sulfhydration sites are identified by mass spectrometry analysis and investigated by site directed mutagenesis. Parkin sulfhydration is markedly depleted in the brains of patients with PD, suggesting that this loss may be pathologic. This implies that H2S donors may be therapeutic.
