WebCystinuria is a disorder of renal and GI tract amino acid transport that also affects lysine, ornithine, and arginine. The four amino acids share a common transport mechanism (discussed previously). Clinically, it presents as urinary stone disease because of the insolubility of cystine. WebNov 16, 2010 · The catalytic potential for H2S biogenesis and homocysteine clearance converge at the active site of cystathionine β-synthase (CBS), a pyridoxal phosphate-dependent enzyme. CBS catalyzes β-replacement reactions of either serine or cysteine by homocysteine to give cystathionine and water or H2S, respectively. WebCystathionine β-synthase (CBS) is a pyridoxal-5‘-phosphate-dependent enzyme that catalyzes the condensation of serine and homocysteine to form cystathionine. … chris slade nfl wife
