Immobilization of Saccharomyces cerevisiae Cystathionine γ-Lyase and Application of the Product to Cystathionine Synthesis [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACT Cystathionine γ-lyase of Saccharomyces cerevisiae was immobilized to aminohexyl-Sepharose through the cofactor pyridoxal 5′-phosphate and was characterized with respect to its cystathionine γ-synthase activity.

Sex-specific dysregulation of cysteine oxidation and the methionine and folate cycles in female cystathionine gamma-lyase null mice: a serendipitous model of the methylfolate trap

Biology Open, 2015
In addition to its role in the endogenous synthesis of cysteine, cystathionine gamma-lyase (CGL) is a major physiological source of the vasorelaxant hydrogen sulfide.

Mucosal acidification increases hydrogen sulfide release through up-regulating gene and protein expressions of cystathionine gamma-lyase in the rat gastric mucosa [PDF]

Iranian Journal of Basic Medical Sciences, 2016
Objective(s): This study was performed to investigate the effects of mucosal acidification on mRNA expression and protein synthesis of cystathionine gamma lyase (CSE), cystathionine beta synthase (CBS), and mucosal release of H2S in gastric mucosa in ...

Two-photon ratiometric imaging of endogenous reactive inorganic sulfur species in the cellular cushion toward formaldehyde

Biosensors and Bioelectronics: X, 2023
To address the potential biological relationship between reactive inorganic sulfur species (RISSs) and formaldehyde, the novel two-photon ratiometric RISSs probes (PH-RISSs) were synthesized practically with high selectivity and sensitivity toward RISSs ...

Harnessing Methylselenol (CH3SeH): A Highly Effective Platform for Stimuli‐Responsive Delivery With Therapeutic Potential

Advanced Science, EarlyView.
Tools for controlled selenol delivery are crucial for exploring Se‐related biology and medicine, but compound platforms for triggerable release of CH3SeH remain lacking. Herein, we report the first general triggered platform (TD‐MSe) for efficient cyclization release of CH3SeH in live cells.

Cystathionine .GAMMA.-lyase activity in the cephamycin C producer Streptomyces lactamdurans.

The Journal of Antibiotics, 1981
Extracts of the cephamycin C producer S. lactamdurans were found to possess cystathionine gamma-lyase activity (E.C. 4.4.1.1). This represents the first demonstration of this enzyme of the reverse transsulfuration pathway in a prokaryotic organism. A likely involvement of reverse transsulfuration in antibiotic synthesis is indicated by the fact that ...

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Hyperhomocysteinemia and Vitamin B Deficiency as Potential Aggravating Factors in Huntington's Disease: A Prospective Monocentric Study

Movement Disorders, EarlyView.
Abstract Background Although not confirmed, some studies have suggested that elevated homocysteine levels are common in patients with Huntington's disease (HD). Its clinical relevance remains unclear. Objectives We aimed to assess vitamin B and homocysteine levels in HD patients and explore the relationships among hyperhomocysteinemia, vitamin B ...

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

Smart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.
