애플리케이션
L-Cystathionine has been used in ultra-performance liquid chromatography for the validation of cystathionine and the correlation of its abundance with vertebrate metamorphosis. It has also been used as an inhibitor of sinusoidal GSH (glutathione) carrier to signify that thiol redox state imbalance is associated with the modulation of autophagy in carcinoma cells.[1]
생화학적/생리학적 작용
L-Cystathionine is an intermediate in the biosynthesis of L-cysteine and methionine.[2][3] It is used as a substrate to differentiate and analyze cystathionine γ-lyase(s).[4] L-Cystathionine is an important non-protein amino acid and is associated with metabolic disorders.[5] In recent studies, L-cystathionine is believed to be the precursor of cyclic imino acid cyclothionine. Cystathioninuria is characterized with imino acid cyclothionine excretion in the urine.[3]

Dietary methionine restriction in Fischer-344 rats favorably influences visceral fat mass, insulin sensitivity, metabolic parameters, and longevity. However, little is known about the effects of methionine restriction on serum methionine and its downstream sulfur amino acids. We investigated the serum

The two disulfide bonds of α-conotoxin ImI, a peptide antagonist of the α7 nicotinic acetylcholine receptor (nAChR), were systematically replaced with isosteric redox-stable cystathionine thioethers. Regioselective thioether formation was accomplished on solid support through substitution of a γ-chlorohomoalanine by an
