Protein ETHE1, mitochondrial, also known as "ethylmalonic encephalopathy 1 protein" and "per sulfide dioxygenase", is a protein that in humans is encoded by the ETHE1 gene located on chromosome 19.[1]

Structure

The human ETHE1 gene consists of 7 exons and encodes for a protein that is approximately 27 kDa in size.

Function

This gene encodes a protein that is expressed in the thyroid.[1]

The ETHE1 protein is thought to localize primarily to the mitochondrial matrix [2][3] and functions as a sulfur dioxygenase. Sulfur deoxygenates are proteins that function in sulfur metabolism. The ETHE1 protein is thought to catalyze the following reaction:

sulfur + O2 + H2O <math>\rightleftharpoons</math> sulfite + 2 H+ (overall reaction)
(1a) glutathione + sulfur <math>\rightleftharpoons</math> S-sulfanylglutathione (glutathione persulfide, spontaneous reaction)
(1b) S-sulfanylglutathione + O2 + H2O <math>\rightleftharpoons</math> glutathione + sulfite + 2 H+[2]

and requires iron[4] and possibly glutathione[4] as cofactors. The physiological substrate of ETHE1 is thought to be glutathione persulfide,[4] an intermediate metabolite involved in hydrogen sulfide degradation.

Clinical significance

Mutations in ETHE1 gene are thought to cause ethylmalonic encephalopathy,[3][5] a rare inborn error of metabolism. Patients carrying ETHE1 mutations have been found to exhibit lower activity of ETHE1 and affinity for the ETHE1 substrate.[4] Mouse models of Ethe1 genetic ablation likewise exhibited reduced sulfide dioxygenase catabolism and cranial features of ethylmalonic encephalopathy.[2] Decrease in sulfide dioxygenase activity results in abnormal catabolism of hydrogen sulfide, an gas-phase signaling molecule in the central nervous system,[4] whose accumulation is thought to inhibit cytochrome c oxidase activity in the respiratory chain of the mitochondrion.[2] However, other metabolic pathways may also be involved that could exert a modulatory effect on hydrogen sulfide toxicity.[6]

Interactions

ETHE1 has been shown to interact with RELA.[7]
