DiseasePARK7_HUMAN Defects in PARK7 are the cause of Parkinson disease type 7 (PARK7) [MIM:606324. A neurodegenerative disorder characterized by resting tremor, postural tremor, bradykinesia, muscular rigidity, anxiety and psychotic episodes. PARK7 has onset before 40 years, slow progression and initial good response to levodopa. Some patients may show traits reminiscent of amyotrophic lateral sclerosis-parkinsonism/dementia complex (Guam disease).[1] [2] [3] [4] [5] [6] [7] [8] FunctionPARK7_HUMAN Protects cells against oxidative stress and cell death.

In this work, we obtained crystals of Arabidopsis thaliana DJ-1d (atDJ-1d) and Homo sapiens DJ-1 (hDJ-1) covalently bound to glyoxylate, an analog of methylglyoxal, forming a hemithioacetal that presumably mimics an intermediate structure in the catalysis from methylglyoxal to lactate. The level of deuteration in lactate formation supported the proton transfer mechanism in the enzyme reaction. Differences in the enantiomeric specificity of D/L-lactacte formation observed in the DJ-1 superfamily proteins were explained by the presence of a His residue in the active site with essential Cys and Glu residues. The model for the stereospecificity was further evaluated by a molecular modeling simulation with methylglyoxal hemithioacetal superimposed on the glyoxylate hemithioacetal. The DJ-1 glyoxalase provides a unique mechanism in understanding the His residue-involved stereospecificity. This article is protected by copyright. All rights reserved.
