생화학적/생리학적 작용
L-Cysteine S-sulfate (LCSS) is used as an NMDA glutamatergic receptor agonist. It serves as a substrate for cystine lyase(s).
Cysteine is one of the functional amino acids that are associated with growth, reproduction, maintenance and immunity. Cysteine is a source of disulfide linkage in protein and is associated with sulfur transport. At physiological pH, cysteine undergoes rapid oxidation to form cystine. Reduced availability of cysteine or cystine, influences leukocyte metabolism. L-Cysteine serves as a precursor for the rate limiting step in glutathione synthesis that occurs in neurons. It donates inorganic sulfate for detoxification reactions. Therefore, L-cysteine might be associated with neuroprotection. It is found to obstruct the entry of heavy metal ions across the blood-brain barrier into the brain. Increased levels of L-cysteine might lead to neurotoxicity.

Escherichia coli has two L-cysteine biosynthetic pathways; one is synthesized from O-acetyl L-serine (OAS) and sulfate by L-cysteine synthase (CysK), and another is produced via S-sulfocysteine (SSC) from OAS and thiosulfate by SSC synthase (CysM). SSC is converted into L-cysteine

Cystine lyase is the enzyme responsible for off-aroma deterioration in fresh unblanched broccoli. In this research, cystine lyase purification from broccoli has been optimized. Only one protein peak with cystine lyase activity was found during purification. Broccoli cystine lyase was

Two distinct forms of desensitization have been characterized for N-methyl-D-aspartate (NMDA) receptors. One form results from a weakening of agonist affinity when channels are activated whereas the other form of desensitization results when channels enter a long-lived nonconducting state. A

Sulfur and selenium occur in proteins as constituents of the amino acids cysteine, methionine, selenocysteine, and selenomethionine. Recent research underscores that these amino acids are truly exceptional. Their redox activity under physiological conditions allows an amazing variety of posttranslational protein
