A common way to synthesize an NHS-activated acid is to mix NHS with the desired carboxylic acid and a small amount of an organic base in an anhydrous solvent. A coupling reagent such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is then added to form a highly reactive activated acid intermediate.
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.

In biochemistry and medicine, glycoprotein IIb/IIIa (GPIIb/IIIa, also known as integrin α IIb β 3) is an integrin complex found on platelets.It is a transmembrane receptor for fibrinogen [1] and von Willebrand factor, and aids platelet activation.
Amino acid activation is a key reaction in many biochemical and metabolic processes. In particular, leucine natural killer treatment of interleukin-18 activated cells triggers the mTORC1 metabolic sensor, which indicates that mTORC1 causes amino acid-driven activation due to a high expression in amino acid transporters.
Calcitriol enters cells and binds to the VDR which forms a complex with its coreceptor RXR and the activated VDR/RXR complex is translocated into the nucleus. [207] The VDR/RXR complex subsequently binds to vitamin D response elements (VDRE) which are specific DNA sequences adjacent to genes, numbers estimated as being in the thousands.
Although contact factors FXII and HK bound PK have been reported to interact with endothelial cells (via gC1q-R), platelets (via Polyphosphate) and Leukocytes; bacteria (Streptococcus pyogenes, Salmonella, and Escherichia coli) and viruses (Hantavirus and Herpes simplex 1 virus) have also been demonstrated to bind to contact factors. [12]
Akt is activated downstream of vascular endothelial growth factor (VEGF) in endothelial cells in the lining of blood vessels, promoting survival and growth. Akt also contributes to angiogenesis by activating endothelial nitric oxide synthase (eNOS), which increases production of nitric oxide (NO).
Once correctly positioned at the membrane via binding of PIP3, Akt can then be phosphorylated by its activating kinases, phosphoinositide-dependent kinase-1 (PDPK1 at threonine 308 in Akt1 and threonine 309 in Akt2) and the mammalian target of rapamycin complex 2 (mTORC2 at serine 473 (Akt1) and 474 (Akt2)) which is found at high levels in the ...
