[3] [1] [4] [5] NV-5138 works by binding to and modulating sestrin2, a cellular sensor protein for the amino acid leucine, which is a natural activator of mammalian target of rapamycin complex 1 (mTORC1) signaling pathway.
A simplified reaction mechanism for N-acetylglutamate synthase (NAGS). Two mechanisms for N-acetyltransferase function have been proposed: a two-step, ping-pong mechanism involving transfer of the relevant acetyl group to an activated cysteine residue [10] and a one-step mechanism through direct attack of the amino nitrogen on the carbonyl group.

NOBS is the main bleach activator used in the U.S.A. and Japan. [4] Compared to TAED, which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water. [5]
In phosphors and scintillators, the activator is the element added as dopant to the crystal of the material to create desired type of nonhomogeneities. In luminescence , only a small fraction of atoms, called emission centers or luminescence centers , emit light.
Tetraacetylethylenediamine, commonly abbreviated as TAED, is an organic compound with the formula (CH 3 C(O)) 2 NCH 2 CH 2 N(C(O)CH 3) 2. It is a white solid commonly used as a bleach activator in laundry detergents and in the production of paper pulp. TAED is synthesized through the acetylation of ethylenediamine.
[1] In contrast to Bay K8644, which is not for clinical use, ambroxol is a frequently used mucolytic drug that triggers lysosomal secretion by mobilizing calcium from acidic calcium stores. [ 2 ] This effect does most likely not occur by a direct interaction between the drug and a lysosomal calcium channel, but indirectly by neutralizing the ...
Carbamoyl phosphate synthetase (glutamine-hydrolysing) (EC 6.3.5.5) is an enzyme that catalyzes the reactions that produce carbamoyl phosphate in the cytosol (as opposed to type I, which functions in the mitochondria).
Phosphofructokinase-1 (PFK-1) is one of the most important regulatory enzymes (EC 2.7.1.11) of glycolysis. It is an allosteric enzyme made of 4 subunits and controlled by many activators and inhibitors. PFK-1 catalyzes the important "committed" step of glycolysis, the conversion of fructose 6-phosphate and ATP to fructose 1,6-bisphosphate and ...
