Chen CNJ, Brown-Borg HM, Rakoczy SG, Ferrington DA, Thompson LV Aging impairs the expression of the catalytic subunit of glutamate cysteine
ligase in soleus muscle under stress.
The overall conformation of this Trp-rich loop changes if the modification of cysteine
CatL is a cysteine
protease abundant in fibroblasts, which is involved in skin structure and functions, including hair follicle morphogenesis, epidermal differentiation, wound healing, and antigen presentation.
the pH in which activity of cysteine
and aspartic peptidases is highest.
Importantly, it is known that the melanogenetic pathway is shifted from eumelanin toward pheomelanin formation when GSH or cysteine
is added to melanocytes or melanoma cell lines.
First, we treated SH-SY5Y cells with N-acetylcysteine (NAC), a derivative of cysteine
that is readily taken up by cells and then rapidly deacetylated, making cysteine
available for GSH synthesis [22, 23].
The profiles of essential amino acids, including cysteine
and tyrosine, of colliroja and Nile tilapia obtained on the basis of the ideal protein concept are shown in Table 2 and Figure 1.
To this end, we found that cells expressing 3-mercaptopyruvate sulfurtransferase (3MST) and cysteine
aminotransferase (CAT) contain increased levels of bound sulfane sulfur.
0 mM cysteine

But supplementing low-calorie, no-protein diets with the sulfur-containing amino acids methionine and cysteine
erases much of that benefit (right bar).
is a sulfur containing amino acids that is unique because of its chemically very reactive sulfhydryl group .
When the thioester gel is treated with cysteine
methyl ester, the thioester bridges are split rapidly and the gel dissolves.
Sulfur is one of the most essential macronutrients required by the plants as it is an important constituent of amino acids such as cysteine
and methionine and also in many metabolites .
Targeting of non-catalytic cysteine
residues with covalent inhibitors is a powerful strategy for optimizing pharmacologic potency and selectivity on challenging targets such as protein kinases.
The researchers added isoniazid and a 'reducing agent' known as cysteine
to the TB in a test tube, expecting the bacteria to develop drug resistance.
