allostery

(əˈlɒstərɪ)
n
the condition of a protein (such as an enzyme) in which the structure and activity of the enzyme are modified by the binding of a metabolic molecule at a site other than the chemically active one

According to the company, the proceeds will be used to accelerate the development of its pipeline, to expand its mutation, allostery and pharmacology computational and discovery platform for identifying and targeting allosteric oncogenic mutations, to establish its new corporate headquarters in Cambridge, MA, advance two-to-three existing development candidates into the clinic as well as to bolster its platform's ability to identify precision medicines for mutant cancers intractable to standard care.
During its stealth stage, Black Diamond built and established proof of concept for its MAP (mutation, allostery and pharmacology) platform to uncover, discover and target allosteric mutant oncogenes.

The differential pleiotrophy of mutations in TF loci has been attributed to an ensemble nature to allostery of intrinsically disordered proteins [49], but alternatively differential pleiotrophy may also be an expected outcome in the model of limited specificity.

Indeed, allostery has remained as a key theory in biology and biochemistry since the quantitative explanation this theory allows regarding the biological activity of oligomeric proteins is fundamental for understanding a variety of cellular processes such as hormone action, gene repression and enzyme kinetics, among others.

As shown in Figure 4(b), the minima of the average commute time (C(i)) indicate the key residues for T-Hb allostery. The profiles of average commute times for [[alpha].sub.1] chain and [[beta].sub.1] chain indicate that Val10 , Leu29 , Arg31 , Thr39 , Cys104 , Val107, His122, and Leu125 in [[alpha].sub.1] chain and Ala27, Val109, Cys112, and Gln127 in [[beta].sub.1] chain are residues with highest communication abilities.
