Architecture and regulation of filamentous human cystathionine beta-synthase

, 2023
Cystathionine beta-synthase (CBS) is an essential metabolic enzyme across all domains of life involved in the production of glutathione, cysteine, and hydrogen sulphide1–4. Human CBS appends to its conserved catalytic domain a regulatory domain that modulates activity by S-adenosyl-L-methionine (SAM) and promotes oligomerization5–12, however the ...

Structural basis for substrate activation and regulation by cystathionine beta-synthase (CBS) domains in cystathionine β-synthase [PDF]

Proceedings of the National Academy of Sciences, 2010
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

Chemical Proteomics Identifies Ketogenesis‐Mediated Cysteine Modifications Regulating Redox Function

Angewandte Chemie, EarlyView.
Herein, we report ketone body induce cysteine modifications beyond lysine acylation, as revealed by integrating chemical proteomics with open‐search methods. Among the modifications, cysteine crotonation (Ccr) was chemically validated by endogenous peptide‐based co‐elution assays.

Cystathionine beta synthase modulates senescence of human endothelial cells

Aging, 2012
Availability of methionine is known to modulate the rate of aging in model organisms, best illustrated by the observation that dietary methionine restriction extends the lifespan of rodents. However, the underlying mechanisms are incompletely understood.

Impact of Varicocele on The Expression of Testicular Enzymes Involved in The Transsulfuration Pathway [PDF]

International Journal of Fertility and Sterility
Background: Oxidative aggression is a hallmark of varicocele and may depend on decreased reactive ability ofthe endogenous antioxidant system following heat stress.

CTH/MPST double ablation results in enhanced vasorelaxation and reduced blood pressure via upregulation of the eNOS/sGC pathway

Frontiers in Pharmacology, 2023
Hydrogen sulfide (H2S), a gasotransmitter with protective effects in the cardiovascular system, is endogenously generated by three main enzymatic pathways: cystathionine gamma lyase (CTH), cystathionine beta synthase (CBS) and 3-mercaptopyruvate ...

Human polycomb 2 protein is a SUMO E3 ligase and alleviates substrate-induced inhibition of cystathionine beta-synthase sumoylation. [PDF]

PLoS ONE, 2008
Human cystathionine beta-synthase (CBS) catalyzes the first irreversible step in the transsulfuration pathway and commits homocysteine to the synthesis of cysteine. Mutations in CBS are the most common cause of severe hereditary hyperhomocysteinemia.

Characterization of hyperglycemia due to sub-chronic administration of red ginseng extract via comparative global proteomic analysis

Scientific Reports, 2021
Ginseng (Panax ginseng Meyer) is commonly used as an herbal remedy worldwide. Few studies have explored the possible physiological changes in the liver although patients often self-medicate with ginseng preparations, which may lead to exceeding the ...

Guidelines for the diagnosis and management of cystathionine beta-synthase deficiency. [PDF]

J Inherit Metab Dis, 2017
AbstractCystathionine beta‐synthase (CBS) deficiency is a rare inherited disorder in the methionine catabolic pathway, in which the impaired synthesis of cystathionine leads to accumulation of homocysteine. Patients can present to many different specialists and diagnosis is often delayed.
