Identification of the allosteric regulatory site of insulysin. [PDF]

open access: yesPLoS ONE, 2011
Insulin degrading enzyme (IDE) is responsible for the metabolism of insulin and plays a role in clearance of the Aβ peptide associated with Alzheimer's disease. Unlike most proteolytic enzymes, IDE, which consists of four structurally related domains and

Enzyme Inhibition by Allosteric Capture of an Inactive Conformation [PDF]

open access: yesJournal of Molecular Biology, 2011
All members of the human herpesvirus protease (HHV Pr) family are active as weakly associating dimers but inactive as monomers. A small-molecule allosteric inhibitor of Kaposi's sarcoma-associated herpesvirus protease (KSHV Pr) traps the enzyme in an inactive monomeric state where the C-terminal helices are unfolded and the hydrophobic dimer interface ...

The allosteric control mechanism of bacterial glycogen biosynthesis disclosed by cryoEM

open access: yesCurrent Research in Structural Biology, 2020
Glycogen and starch are the major carbon and energy reserve polysaccharides in nature, providing living organisms with a survival advantage. The evolution of the enzymatic machinery responsible for the biosynthesis and degradation of such polysaccharides,

Bioinformatic Scaling of Allosteric Interactions in Biomedical Isozymes [PDF]

open access: yes, 2015
Allosteric (long-range) interactions can be surprisingly strong in proteins of biomedical interest. Here we use bioinformatic scaling to connect prior results on nonsteroidal anti-inflammatory drugs to promising new drugs that inhibit cancer cell metabolism.

Deciphering the allosteric regulation of mycobacterial inosine-5′-monophosphate dehydrogenase

open access: yesNature Communications
Allosteric regulation of inosine 5′-monophosphate dehydrogenase (IMPDH), an essential enzyme of purine metabolism, contributes to the homeostasis of adenine and guanine nucleotides. However, the precise molecular mechanism of IMPDH regulation in bacteria

Notes on stochastic (bio)-logic gates: the role of allosteric cooperativity [PDF]

open access: yes, 2014
Recent experimental breakthroughs have finally allowed to implement in-vitro reaction kinetics (the so called {\em enzyme based logic}) which code for two-inputs logic gates and mimic the stochastic AND (and NAND) as well as the stochastic OR (and NOR). This accomplishment, together with the already-known single-input gates (performing as YES and NOT),

Fractal mechanisms for the allosteric effects of proteins and enzymes

open access: yesBiophysical Journal, 1990
Investigations have been made on the reaction kinetics of proteins and enzymes by the statistical methods of random walks on fractal structures. From the point of view of networks of Trap (R) and Free (T) sites, the relationships between the Hill coefficients (h) and the fractal (df) as well as spectral (ds) dimensions of protein molecules are obtained.

PCR-like cascade reactions in the context of an allosteric enzyme mimic.

open access: yesJournal of the American Chemical Society, 2008
A supramolecular allosteric catalyst that exhibits a PCR-like cascade reaction is reported. The complex is triggered by a reaction with an acetate ion, which turns on a catalytic cascade that exponentially increases acetate ion concentration through an ...

High Resolution Crystal Structure of the Pyruvate Kinase Tetramer in Complex with the Allosteric Activator Mitapivat/AG-348

open access: yesCrystals
Pyruvate kinase (PK) deficiency is a rare genetic disorder that affects this critical enzyme within the glycolysis pathway. In recent years, Mitapivat (MTPV, AG-348) has emerged as a notable allosteric activator for treating PK deficiency.
