WebCystathionine beta Synthase Assay Kit See all CBS kits Detection method Fluorescent Sample type Cell culture supernatant, Tissue, Adherent cells, Suspension cells Product overview Cystathionine beta Synthase Assay Kit (ab241043) utilizes cysteine and homocysteine as substrates to produce H2S. WebHomocystinuria is caused by problems with the enzyme “cystathionine beta-synthase” (CBS). In people with homocystinuria, CBS is either missing or not working properly. This enzyme’s job is to break down methionine. When the CBS enzyme is not working correctly, methionine and another amino acid, homocystine, build up in the blood and cause …
WebFeb 9, 2024 · Cystathionine beta-synthase deficiency [CBS] syndrome or classical homocystinuria is a multisystem disorder caused by the deficiency of CBS, an enzyme in the transsulfuration pathway of homocysteine metabolism. It was first described in 1960 as a variant of Marfan syndrome. The true population frequency is unknown, with estimates …
