SUOX (Sulfite Oxidase): SUOX codes for an enzyme essential in the metabolism of sulphur-containing amino acids. It catalyses the final step in the breakdown of cysteine and methionine by converting sulphite into sulphate, which is then excreted in the urine. Proper SUOX activity prevents the accumulation of sulphite, which can cause neurological damage and physical abnormalities known as sulphite oxidase deficiency, highlighting the enzyme’s vital role in amino acid metabolism and the prevention of neurotoxicity.
