Light-regulated allosteric switch enables temporal and subcellular control of enzyme activity
Engineered allosteric regulation of protein activity provides significant advantages for the development of robust and broadly applicable tools. However, the application of allosteric switches in optogenetics has been scarce and suffers from critical ...

Rational engineering of enzyme allosteric regulation through sequence evolution analysis.
Control of enzyme allosteric regulation is required to drive metabolic flux toward desired levels. Although the three-dimensional (3D) structures of many enzyme-ligand complexes are available, it is still difficult to rationally engineer an ...

Lanthanide complexes are ideal donors for FRET (Förster resonance energy transfer) assays with a variety of applications from easy‐to‐use quantitation of proteins to sophisticated experiments giving real‐time information on the movement of proteins. This Review article introduces the principles of using such assays before surveying the full scope of ...

Functional selectivity of insulin receptor revealed by aptamer-trapped receptor structures
DNA aptamers can activate insulin receptor as selective agonists or positive allosteric modulators. Here, authors determine structures of the insulin receptor bound to aptamers and provide a basis for the selective activation or allosteric regulation of ...

Prediction and confirmation of a switch-like region within the N-terminal domain of hSIRT1
Many proteins display conformational changes resulting from allosteric regulation. Often only a few residues are crucial in conveying these structural and functional allosteric changes.

Binding leverage as a molecular basis for allosteric regulation.
Allosteric regulation involves conformational transitions or fluctuations between a few closely related states, caused by the binding of effector molecules.

Information propagation in time through allosteric signaling [PDF]
Naively, one expects the information communicated by an enzyme downstream within a signaling network, in which the enzyme is embedded, to grow monotonically with the enzyme's rate of product formation. However, here we observe that this does not necessarily hold true for allosterically regulated enzymes, often observed in signaling networks.

The allosteric regulation of the bienzyme complex imidazole glycerol phosphate synthase (HisFH) remains to be elucidated. Here, the authors provide structural insights into the dynamic allosteric mechanism by which ligand binding to the cyclase and ...

Prediction of allosteric sites and mediating interactions through bond-to-bond propensities [PDF]
Allosteric regulation is central to many biochemical processes. Allosteric sites provide a target to fine-tune protein activity, yet we lack computational methods to predict them. Here, we present an efficient graph-theoretical approach for identifying allosteric sites and the mediating interactions that connect them to the active site.
