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 ...

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

Structural basis for substrate activation and regulation by cystathionine beta-synthase (CBS) domains in cystathionine β-synthase [PDF]
The catalytic potential for H 2 S 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 H 2

Interactions of the Gasotransmitters Contribute to Microvascular Tone (Dys)regulation in the Preterm Neonate [PDF]
Background & Aims Hydrogen sulphide (H2S), nitric oxide (NO), and carbon monoxide (CO) are involved in transitional microvascular tone dysregulation in the preterm infant; however there is conflicting evidence on the interaction of these ...

Vascular presentation of cystathionine beta‐synthase deficiency in adulthood [PDF]
AbstractSeveral recent studies describing a solely vascular presentation of cystathionine beta‐synthase (CBS) deficiency in adulthood prompted us to analyze the frequency of patients manifesting with vascular complications in the Czech Republic. Between 1980 and 2009, a total of 20 Czech patients with CBS deficiency have been diagnosed yielding an ...

Low frequency dynamics of Cystathionine beta-synthase [PDF]
Femtosecond coherence spectroscopy is used to study the low frequency dynamics of cystathionine beta-synthase (CBS). CBS is a pyridoxal-5′-phosphate-dependent heme enzyme with cysteine and histidine axial ligands that catalyzes the condensation of serine and homocysteine to form cystathionine.

Cystathionine beta-synthase (CBS) contributes to advanced ovarian cancer progression and drug resistance. [PDF]
Epithelial ovarian cancer is the leading cause of gynecologic cancer deaths. Most patients respond initially to platinum-based chemotherapy after surgical debulking, however relapse is very common and ultimately platinum resistance emerges. Understanding

The endogenous production of hydrogen sulphide in intrauterine tissues [PDF]
Background: Hydrogen sulphide is a gas signalling molecule which is produced endogenously from L-cysteine via the enzymes cystathionine beta-synthase (CBS) and cystathionine gamma-lyase (CSE).

One-carbon cycle alterations induced by Dyrk1a dosage
Hyperhomocysteinemia due to cystathionine beta synthase deficiency confers diverse clinical manifestations. It is characterized by elevated plasma homocysteine levels, a common amino acid metabolized by remethylation to methionine or transsulfuration to ...
