Crystal structure of human persulfide dioxygenase: structural basis of ethylmalonic encephalopathy
The ethylmalonic encephalopathy protein 1 (ETHE1) catalyses the oxygen-dependent oxidation of glutathione persulfide (GSSH) to give persulfite and glutathione. Mutations to the hETHE1 gene compromise sulfide metabolism leading to the genetic disease ethylmalonic encephalopathy. hETHE1 is a mono-iron binding member of the metallo-β-lactamase (MBL) fold superfamily. We report crystallographic ana...
متن کاملEthylmalonic encephalopathy and SCAD deficiency
Ethylmalonic encephalopathy is a devastating, infantile, autosomal recessive, metabolic disorder caused by defects in the mitochondrial sulfur dioxygenase, ETHE1, and characterized by ethylmalonic and methylsuccinic aciduria, lactic acidemia associated with developmental delay, orthostatic acrocyanosis, recurrent petechiae, chronic diarrhea, and abnormalities on brain MRI. The authors also repo...
متن کاملNeurological and Vascular Manifestations of Ethylmalonic Encephalopathy
Objective Ethylmalonic encephalopathy (EE) is a severe mitochondrial disease of early infancy clinically characterized by a combination of developmental delay, progressive pyramidal signs, and vascular lesions including petechial purpura, orthostatic acrocyanosis, and chronic hemorrhagic diarrhea. Biochemical hallmarks of the disease are persistently high level of lactate, and C4-C5-acylcarniti...
متن کاملEthylmalonic encephalopathy. Another patient from Kuwait.
We report a Kuwaiti girl with ethylmalonic encephalopathy. She presented at the age of 4 months with chronic mucoid diarrhea and delayed psychomotor development, and at 6 months she developed myoclonic epilepsy. She was found to have central hypotonia with pyramidal tract signs, acrocyanosis, and petechiae. Plasma lactate level was elevated. Blood spot and urine for organic acids results were c...
متن کاملCorrection: High Resolution Crystal Structure of Human β-Glucuronidase Reveals Structural Basis of Lysosome Targeting
Human β-glucuronidase (GUS) cleaves β-D-glucuronic acid residues from the non-reducing termini of glycosaminoglycan and its deficiency leads to mucopolysaccharidosis type VII (MPSVII). Here we report a high resolution crystal structure of human GUS at 1.7 Å resolution and present an extensive analysis of the structural features, unifying recent findings in the field of lysosome targeting and gl...
