NOBS was developed by Procter & Gamble in 1983 [2] and was first used in American laundry detergents in 1988. [3] 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
In the N-terminal region at amino acid position 55-61 the cdh1 protein contains a C-Box motif, which is required for the association with the APC/c complex. Especially the residue R56 seems to be important for the binding to APC/c in vitro and Cdh1 function in vivo. [9] [10] Cdh1 contains multiple phosphorylation sites for the kinase cdc28 ...
The electronic configuration of the activator depends on its oxidation state and is crucial for the light emission. Oxidation of the activator is one of the common mechanisms of phosphor degradation. The distribution of the activator in the crystal is also of high importance.
[2] [3] [4] The activity of activators is controlled by the ability of the activator to bind to its regulatory site along the DNA. [2] [3] [4] The DNA-binding domain of the activator has an active form and an inactive form, which are controlled by the binding of molecules known as allosteric effectors to the allosteric site of the activator.

Sirtuin-activating compounds (STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases.
One common strategy is to form stable metal complexes. One example is reported by Milstein and coworkers, in which the C(sp 2)–C(sp 3) bond of bisphosphine ligands was selectively cleaved by a number of metals to afford stable pincer complexes under mild conditions. [4] [5] [6] C-C bond activation driven by the formation of stable metal complexes
[6] Drugs in the oxime class (e.g., Pralidoxime) reactivate AChE by removing the OP. Oximes have a higher affinity for phosphorylation than the serine residue in the AChE active site, causing the OP to detach from the AChE enzyme, freeing its active site and restoring function.
2Na 2 CO 3 ∙3H 2 O 2 → 2Na 2 CO 3 + 3H 2 O 2. In a basic wash solution, hydrogen peroxide loses a proton and is converted to the perhydroxyl anion: H 2 O 2 ⇌ H + + HO 2 −. The perhydroxyl anion then attacks the activator, forming a peroxy acid: HO 2 − + RC(O)X → X − + RC(O)O 2 H
