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. It is considered a biochemical anomaly. This is b… WebWe reveal that, in normoxia, enzymatic action of cystathionine β-synthase (CBS) produces H 2 S, which persulfidates prolyl hydroxylase 2 (PHD2) at residues Cys 21 and Cys 33 (zinc finger motif), augmenting prolyl hydroxylase activity.

Cystathionine is an intermediary metabolite that is formed in the sequential enzymatic conversion of methionine to cysteine. WebOrphanet. 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 ... iron plates for sale
