Ethylmalonic encephalopathy (Homo sapiens)
From WikiPathways
Description
Cysteine is converted into pyruvate and hydrogen sulfide (H2S) through desulphuration and deamination. Then, H2S is oxidised by SQR, after which ETHE1 takes care of converting into sulfite (SO3 2-). One disorder named Ethylmalonic encephalopathy (EE) is linked to this pathway, a rare mitochondrial disease caused by variants within the ETHE1 gene.
