Direct Zinc Finger Protein Persulfidation by H\textsubscript2 S Is Facilitated by Zn\textsuperscript2+

open access: yes, 2019
H 2 S is a gaseous signaling molecule that modifies cysteine residues in proteins to form persulfides (P-SSH). One family of proteins modified by H 2 S are zinc finger (ZF) proteins, which contain multiple zinc-coordinating cysteine residues.

Persulfidome of Sweet Pepper Fruits during Ripening: The Case Study of Leucine Aminopeptidase That Is Positively Modulated by H2S

open access: yesAntioxidants
Protein persulfidation is a thiol-based oxidative posttranslational modification (oxiPTM) that involves the modification of susceptible cysteine thiol groups present in peptides and proteins through hydrogen sulfide (H2S), thus affecting their function ...

Quantification of persulfidation on specific proteins: are we nearly there yet? [PDF]

open access: yes
Hydrogen sulfide (H2S) played a pivotal role in the early evolution of life on Earth before the predominance of atmospheric oxygen. The legacy of a persistent role for H2S in life’s processes recently emerged through its discovery in modern biochemistry ...

Versatile roles of cysteine persulfides in tumor biology

open access: yesCurrent Opinion in Chemical Biology
Rewiring the transsulfuration pathway is recognized as a rapid adaptive metabolic response to environmental conditions in cancer cells to support their increased cysteine demand and to produce Reactive Sulfur Species (RSS) including hydrogen sulfide (H2S) and cysteine persulfide.

Polysulfide and persulfide-mediated activation of the PERK-eIF2α-ATF4 pathway increases Sestrin2 expression and reduces methylglyoxal toxicity

open access: yesRedox Biology
Unfolded protein response (UPR) is activated in cells under endoplasmic reticulum (ER) stress. One sensor protein involved in this response is PERK, which is activated through its redox-dependent oligomerization.

Insights from Structure-Based Simulations into the Persulfidation of Uridine Diphosphate-Glycosyltransferase71c5 Facilitating the Reversible Inactivation of Abscisic Acid

open access: yes
The action of abscisic acid (ABA) is closely related to its level in plant tissues. Uridine diphosphate-glycosyltransferase71c5 (UGT71C5) was characterized as a major UGT enzyme to catalyze the formation of the ABA-glucose ester (ABA-GE), a reversible ...

Self-S-sulfonation in a bacterial persulfide dioxygenase mediates thiol persulfide detoxification

open access: yes
A ubiquitous class of non-heme Fe(II) enzymes, the persulfide dioxygenases (PDOs), provide protection against hydrogen sulfide (H2S) poisoning. The PDO in humans is a single-domain enzyme, while bacterial PDOs, such as CstB of Staphylococcus aureus, are often fused to a sulfurtransferase (rhodanese) module.

Sulfite oxidase deficiency causes persulfidation loss and hydrogen sulfide release [PDF]

open access: yes
Sulfite oxidase (SOX) deficiency is a rare inborn error of cysteine metabolism resulting in severe neurological damage. In patients, sulfite accumulates to toxic levels, causing a rise in the downstream products S-sulfocysteine, which mediates ...
