WebAbstract. Cysteine auxotrophy and absence of cystathionase (CSE) has been associated with certain human and rodent leukemic cell lines. To determine whether this state was a marker of malignant transformation or of cellular differentiation, CSE content was measured in 16 well characterized human leukemia-lymphoma cell lines. 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 ).

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. WebIn cystathioninuria, the enzyme cystathionine gamma-lyase, which normally catalyzes the hydrolysis of cystathionine to cysteine, is defective. As a result, abnormally high …
