Cystathionine beta-synthase deficiency causes fat loss in mice. [PDF]
Cystathionine beta synthase (CBS) is the rate-limiting enzyme responsible for the de novo synthesis of cysteine. Patients with CBS deficiency have greatly elevated plasma total homocysteine (tHcy), decreased levels of plasma total cysteine (tCys), and ...

H2S and homocysteine control a novel feedback regulation of cystathionine beta synthase and cystathionine gamma lyase in cardiomyocytes [PDF]
Hydrogen sulfide (H2S), a cardioprotective gas, is endogenously produced from homocysteine by cystathionine beta synthase (CBS) and cystathionine gamma lyase (CSE) enzymes.

Homocystinuria due to cystathionine beta-synthase (CBS) deficiency in Russia: Molecular and clinical characterization [PDF]
We present the results of the 45-year clinical observation of 27 Russian homocystinuria patients. We made a mutation analysis of the CBS gene for thirteen patients from eleven unrelated genealogies.

Unraveling CBS Mutations and Their Clinical Impact in a Chinese Family With Classical Homocystinuria [PDF]
Background Classical homocystinuria (HCU), caused by cystathionine beta‐synthase (CBS) deficiency, exhibits significant geographic variability in its mutational spectrum.

Recent therapeutic approaches to cystathionine beta-synthase-deficient homocystinuria. [PDF]
Cystathionine beta‐synthase (CBS)‐deficient homocystinuria (HCU) is the most common inborn error of sulfur amino acid metabolism. The pyridoxine non‐responsive form of the disease manifests itself by massively increasing plasma and tissue concentrations of homocysteine, a toxic intermediate of methionine metabolism that is thought to be the major cause

Recurrent venous thrombosis in an adolescent male with CBS mutation and persistent antiphospholipid antibody positivity: a case report [PDF]
Homocysteine (Hcy) contributes to endothelial dysfunction and impaired thrombolysis, and genetic polymorphisms that elevate plasma Hcy concentrations have been linked to an increased risk of thrombosis. Notably, mutations in the cystathionine β-synthase (

Role of 3-Mercaptopyruvate Sulfurtransferase (3-MST) in Physiology and Disease
3-mercaptopyruvate sulfurtransferase (3-MST) plays the important role of producing hydrogen sulfide. Conserved from bacteria to Mammalia, this enzyme is localized in mitochondria as well as the cytoplasm. 3-MST mediates the reaction of 3-mercaptopyruvate

Huntingtin interacts with cystathionine beta-synthase [PDF]
We have screened a rat brain library to identify proteins which interact with the 5'-end of huntingtin (amino acids 1-171), including the polyglutamine tract, in the yeast two-hybrid system. We detected an interaction with cystathionine beta-synthase (CBS) [L-serine hydrolyase (adding homocysteine), EC 4.2.1.22], which was confirmed in vitro using His ...

Cystathionine beta synthase expression in mouse retina. [PDF]
Abstract Purpose: Cystathionine β-synthase (CBS), a key enzyme in the transsulfuration metabolic pathway, converts homocysteine to cystathionine, which is converted to cysteine required for the synthesis of major retinal antioxidant glutathione (GSH).

Activation of mutant enzyme function in vivo by proteasome inhibitors and treatments that induce Hsp70. [PDF]
Missense mutant proteins, such as those produced in individuals with genetic diseases, are often misfolded and subject to processing by intracellular quality control systems. Previously, we have shown using a yeast system that enzymatic function could be
