Accumulating evidence suggests that hydrogen sulfide (H2S) is a gaseous signaling molecule that regulates diverse cellular signaling pathways through persulfidation, which involves the post translatio...
Prospective study of serum cysteine and cysteinylglycine and cancer of the head and neck, esophagus, and stomach in a cohort of male smokers
cysteine esophageal neoplasms head and neck neoplasms stomach neoplasms upper gastrointestinal tract cancers
2018/12/14
Background:The nonessential amino acid cysteine is known to be involved in many antioxidant and anticarcinogenic pathways. Cysteinylglycine is a pro-oxidant metabolite of glutathione and a precursor o...
Dietary cysteine reduces the methionine requirement in men
amino acid requirement stable isotopes methionine
2016/6/14
Despite early evidence suggesting that dietary cysteine
has a sparing effect on methionine requirements, some recent
reports question the existence of a measurable sparing capacity.
Lifestyle and cardiovascular disease risk factors as determinants of total cysteine in plasma: the Hordaland Homocysteine Study
Hordaland Homocysteine Study Norway Plasma total cysteine
2016/6/2
Plasma total homocysteine (tHcy) is a cardiovascular
disease risk factor and is related to several components of
the established cardiovascular disease risk profile. Cysteine is

Site-Specific Conversion of Cysteine Thiols into Thiocyanate Creates an IR Probe for Electric Fields in Proteins
food packaging perfluorinated dietary intake human exposure
2016/5/24
The nitrile stretching mode of the thiocyanate moiety is a nearly ideal probe for measuring the local electric field arising from the organized environment of the interior of a protein. Nitriles were ...
19F NMR of Trifluoroacetyl-Labeled Cysteine Mutants of Myoglobin:Structural Probes of Nitric Oxide Bound to the H93G Cavity Mutant
19F NMR Trifluoroacetyl Cysteine Mutants Myoglobin Nitric Oxide H93G Cavity Mutant
2016/5/23
Nitric oxide (NO) binds to the myoglobin (Mb) cavity mutant, H93G, forming either a 5- or 6-coordinate Fe--NO heme complex. The H93G mutation replaces the proximal histidine of Mb with glycine, allowi...
