Effects of isocoumarins isolated from Paepalanthus bromelioides on mitochondria: Uncoupling, and induction/inhibition of mitochondrial permeability transition
(Elsevier B.V., 2006-06-10)
Isolated mitochondria may undergo uncoupling, and in presence of Ca2+ at different conditions, a mitochondrial permeability transition (MPT) linked to protein,thiol oxidation, and demonstrated by CsA-sensitive mitochondrial ...

Thiol oxidation by nitrosative stress: Cellular localization in human spermatozoa
(Informa Healthcare, 2016-09)
Peroxynitrite is a highly reactive nitrogen species and when it is generated at high levels it causes nitrosative stress, an important cause of impaired sperm function. High levels of peroxynitrite have been shown to ...
Thiol-disulfide proteins of stallion epididymal spermatozoa
(Elsevier, 2015)
Mitochondrial membrane protein thiol reactivity with N-ethylmaleimide or mersalyl is modified by Ca2+: Correlation with mitochondrial permeability transition
(Elsevier Science BvAmsterdamHolanda, 1997)
Conferring specificity in redox pathways by enzymatic thiol/disulfide exchange reactions
(Taylor & Francis Ltd, 2016-02-01)
Thiol-disulfide exchange reactions are highly reversible, displaying nucleophilic substitutions mechanism (S(N)2 type). For aliphatic, low molecular thiols, these reactions are slow, but can attain million times faster ...
Thiol redox biochemistry: Insights from computer simulations
(Springer, 2014-03)
Thiol redox chemical reactions play a key role in a variety of physiological processes, mainly due to the presence of low-molecular-weight thiols and cysteine residues in proteins involved in catalysis and regulation. ...
Mechanisms underlying iron and copper ions toxicity in biological systems: Pro-oxidant activity and protein-binding effects
(2010)
Iron and copper ions, in their unbound form, may lead to the generation of reactive oxygen species via Haber-Weiss and/or Fenton reactions. In addition, it has been shown that copper ions can irreversibly and non-specifically ...
