Cystathionine β-synthase (human)

1987
Publisher Summary Cystathionine β-synthase (L-serine hydro-lyase [adding homocysteine]) is a pyridoxal 5’-phosphate-dependent enzyme in the transsuifuration pathway of higher eukaryotes which catalyzes the condensation of serine and homocysteine to form cystathionine.

Marine natural products as inhibitors of cystathionine beta-synthase activity

Bioorganic & Medicinal Chemistry Letters, 2015
A library consisting of characterized marine natural products as well as synthetic derivatives was screened for compounds capable of inhibiting the production of hydrogen sulfide (H2S) by cystathionine beta-synthase (CBS). Eight hits were validated and shown to inhibit CBS activity with IC50 values ranging from 83 to 187μM.

Cystathionine beta synthase: Gene dosage effect in trisomy 21

Biochemical and Biophysical Research Communications, 1985
The enzymatic activity of cystathionine beta synthase has been studied in fibroblasts of nine patients with regular trisomy 21. An excess of CBS activity was found in trisomy 21 with a trisomy 21/normal ratio equal to 1.66. A 1.04 ratio was found in 21q21----21 p ter monosomy; a 1.04 and 0.99 ratio was found in two 21 qter----21q22.3 monosomies; a 1.14

Cystathionine beta-synthase and gamma-cystathionase in helminths.

Parasitology research, 1992
The activities of gamma-cystathionase and cystathionine beta-synthase were investigated in a range of gastrointestinal, free-living and entomophagous nematodes. Although nematode gamma-cystathionase used the same range of substrates as the mammalian hepatic enzyme, its activity was extremely low and there were significant interspecies variations with ...

Potential Pharmacological Chaperones for Cystathionine Beta-Synthase-Deficient Homocystinuria

2017
Classical homocystinuria (HCU) is the most common loss-of-function inbornerror of sulfur amino acid metabolism. HCU is caused by a deficiency in enzymaticdegradation of homocysteine, a toxic intermediate of methionine transformationto cysteine, chiefly due to missense mutations in the cystathionine betasynthase(CBS) gene.
