ETHE1 encodes the human gene, Ethylmalonic encephalopathy 1. It may also be known as: Persulfide dioxygenase ETHE1, mitochondrial; Ethylmalonic encephalopathy protein 1; Hepatoma subtracted clone one protein; Sulfur dioxygenase ETHE1; Persulfide dioxygenase ETHE1, mitochondrial ; HSCO; YF13H12. The encoded protein is an enzyme with an amino acid length of 254 and a mass of 27.9 kDa. ETHE1 is a member of the Metallo-beta-lactamase superfamily, Glyoxalase II family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Arabidopsis, Zebrafish, Frog, Chicken.
