Cysteine residues in signal transduction and its relevance in pancreatic beta cells

open access: yesFrontiers in Endocrinology, 2023
Cysteine is one of the least abundant but most conserved amino acid residues in proteins, playing a role in their structure, metal binding, catalysis, and redox chemistry.

The Capacity to Produce Hydrogen Sulfide (H2S) via Cysteine Degradation Is Ubiquitous in the Human Gut Microbiome

open access: yesbioRxiv, 2021
As one of the three mammalian gasotransmitters, hydrogen sulfide (H2S) plays a major role in maintaining physiological homeostasis. Endogenously produced H2S plays numerous beneficial roles including mediating vasodilation and conferring neuroprotection.

Understanding the role of cysteine in ferroptosis: progress & paradoxes

open access: yesThe FEBS Journal, 2021
Cysteine is a conditionally essential amino acid required for the synthesis of proteins and many important intracellular metabolites. Cysteine depletion can trigger iron‐dependent nonapoptotic cell death–ferroptosis.

The Homology Modeling and Docking Investigation of Human Cathepsin B [PDF]

open access: yesInternational Journal of Medical Toxicology and Forensic Medicine, 2020
Background: Cathepsin B comprises a group of lysosomal cysteine proteases belonging to the Papain family; it has an intracellular function in the process of protein catabolism, antigen processing in the immune response, and Alzheimer’s disease.

Non-canonical glutamate-cysteine ligase activity protects against ferroptosis

open access: yesbioRxiv, 2020
Cysteine is required for maintaining cellular redox homeostasis in both normal and transformed cells. Deprivation of cysteine induces the iron-dependent form of cell death known as ferroptosis; however, the metabolic consequences of cysteine starvation ...

Preoperative Short‐Term Restriction of Sulfur‐Containing Amino Acid Intake for Prevention of Acute Kidney Injury After Cardiac Surgery: A Randomized, Controlled, Double‐Blind, Translational Trial

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Acute kidney injury (AKI) is a major risk factor for chronic kidney disease and increased mortality. Until now, no compelling preventive or therapeutic strategies have been identified. Dietary interventions have been proven highly effective in

Cysteine and homocysteine as biomarker of various diseases

open access: yesFood Science & Nutrition, 2020
Cysteine and homocysteine (Hcy), both sulfur‐containing amino acids (AAs), produced from methionine another sulfur‐containing amino acid, which is converted to Hcy and further converted to cysteine.

Succination of Protein Thiols in Human Brain Aging

open access: yesFrontiers in Aging Neuroscience, 2020
Human brain evolution toward complexity has been achieved with increasing energy supply as the main adaptation in brain metabolism. Energy metabolism, like other biochemical reactions in aerobic cells, is under enzymatic control and strictly regulated ...
