WebMar 19, 2024 · Cystathionine-β-synthase (CBS) CBS is the first enzyme in the trans-sulfuration pathway and produces H 2 S mainly through catalyzing homocysteine and cysteine. In the presence of homocysteine, CBS catalyzes its condensation with serine to form cystathionine, which is then cleaved by cystathionine γ-lyase (CTH) to form … WebJan 29, 2024 · We found changes in one-carbon metabolites that indicate inefficient activation of cystathionine β-synthase (CBS) in AD and PD subjects with dementia, the latter seemingly accompanied by a restricted re-methylation flow. Levodopa–carbidopa is known to reduce available vitamin B6, which would explain the hindered CBS activity. ...
