Cystathioninuria is an autosomal recessive disorder caused by cystathionine gamma-lyase deficiency. It is usually pyridoxine-dependent, but in very rare cases it may be non-dependent. It is generally considered to be a benign condition without pathogenic relevance. However, association of cystathioninuria with intellectual impairment ...
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 ). WebAug 12, 2024 · The CTH gene encodes cystathionine gamma-lyase (EC 4.4.1.1.), an enzyme that transforms cystathionine derived from methionine into cysteine. This reaction is preceded by the condensation of homocysteine and serine to form cystathionine, a process catalyzed by cystathionine beta-synthase (CBS; 613381).Cysteine is …
