Allosteric regulation of kinase activity in living cells. [PDF]
The dysregulation of protein kinases is associated with multiple diseases due to the kinases' involvement in a variety of cell signaling pathways. Manipulating protein kinase function, by controlling the active site, is a promising therapeutic and investigative strategy to mitigate and study diseases.

The Allosteric Regulation of Pyruvate Kinase [PDF]
Pyruvate kinase (PK) is critical for the regulation of the glycolytic pathway. The regulatory properties of Escherichia coli were investigated by mutating six charged residues involved in interdomain salt bridges (Arg(271), Arg(292), Asp(297), and Lys(413)) and in the binding of the allosteric activator (Lys(382) and Arg(431)).

The allosteric regulation of pyruvate kinase [PDF]
Crystallographic and mutagenesis studies have unravelled the general features of the allosteric transition mechanism in pyruvate kinase. The enzyme displays a dramatic conformational change in going from the T‐ to the R‐state. All three domains forming each subunit of the tetrameric enzyme undergo simultaneous and concerted rotations, in such a way ...

Modes of allosteric regulation of the ubiquitination machinery [PDF]
Ubiquitination is a post-translational modification crucial for cellular signaling. A diverse range of enzymes constitute the machinery that mediates attachment of ubiquitin onto target proteins. This diversity allows the targeting of various proteins in a highly regulated fashion.

Computational Analysis of Residue Interaction Networks and Coevolutionary Relationships in the Hsp70 Chaperones: A Community-Hopping Model of Allosteric Regulation and Communication. [PDF]
Allosteric interactions in the Hsp70 proteins are linked with their regulatory mechanisms and cellular functions. Despite significant progress in structural and functional characterization of the Hsp70 proteins fundamental questions concerning modularity

Activity modulation and allosteric control of a scaffolded DNAzyme using a dynamic DNA nanostructure. [PDF]
Recognition of the fundamental importance of allosteric regulation in biology dates back to not long after its discovery in the 1960s. Our ability to rationally engineer this potentially useful property into normally non-allosteric catalysts, however ...

Molecular Structure Underlying the Allosteric Mechanism of Caffeine Detection in Taste Sensor
The use of taste sensors with lipid/polymer membranes is one of the methods to evaluate taste. As previously reported, taste sensors can detect non-charged substances such as caffeine by modifying the lipid/polymer membranes with hydroxybenzoic acids ...
