WebSep 16, 2013 · Cystathionine β-synthase (CBS; E.C. 4.2.1.22) is a pyridoxal-5′-phosphate (PLP)–dependent enzyme that plays a pivotal role in sulfur amino acid metabolism. CBS catalyzes a β-replacement reaction in which the hydroxyl group of l -serine (Ser) is replaced by l -homocysteine (Hcy), yielding cystathionine (Cth) ( 1 ).

Cystathionine is an intermediary metabolite that is formed in the sequential enzymatic conversion of methionine to cysteine. WebCysteine is the rate-limiting substrate in the synthetic pathway for glutathione in the eye. Glutathione is an antioxidant that protects crystallins in the eye from reactive oxygen species; denatured crystallins can lead to cataracts. Cystathionase is also a target for reactive oxygen species.
WebNature. Cystathioninuria, also called cystathionase deficiency, is an autosomal recessive metabolic disorder. It is characterized by an abnormal accumulation of plasma cystathionine leading to excess cystathionine in the urine. Hereditary cystathioninuria is associated with the reduced activity of the enzyme cystathionine gamma-lyase. WebCystathionine beta-synthase (CBS) deficiency is a rare inherited disorder in the methionine catabolic pathway, in which the impaired synthesis of cystathionine leads to accumulation of homocysteine. Patients can present to many different specialists and diagnosis is often delayed. Severely affected …
