Targeting allosteric sites is gaining increasing recognition as a strategy for modulating the activity of enzymes, especially in drug design. Here we investigate the mechanisms of allosteric regulation of cathepsin K as a representative of cysteine ...

Multiple conformations in solution of the maize C4-phosphoenolpyruvate carboxylase isozyme
The photosynthetic phosphoenolpyruvate carboxylase isozyme from C4 plants (PEPC-C4) has a complex allosteric regulation, involving positive cooperativity in binding the substrate phosphoenolpyruvate as well as positive and negative allosteric effectors ...

Molecular mechanism of a covalent allosteric inhibitor of SUMO E1 activating enzyme
E1 enzymes activate ubiquitin (Ub) and ubiquitin-like modifiers (Ubls) in the first step of Ub/Ubl conjugation cascades and represent potential targets for therapeutic intervention in cancer and other life-threatening diseases.

Organism-adapted specificity of the allosteric regulation of pyruvate kinase in lactic acid bacteria. [PDF]
Pyruvate kinase (PYK) is a critical allosterically regulated enzyme that links glycolysis, the primary energy metabolism, to cellular metabolism. Lactic acid bacteria rely almost exclusively on glycolysis for their energy production under anaerobic ...

Understanding allosteric and cooperative interactions in enzymes [PDF]
The paper that introduced biochemists to the idea of allosteric feedback inhibition [Monod J, Changeux J‐P & Jacob F (1963) J Mol Biol 6, 306–329] is now 50 years old, and the two papers on models for enzyme cooperativity that followed it [Monod J, Wyman J & Changeux J‐P (1965) J Mol Biol 12, 88–118; Koshland DE, Némethy G & Filmer D (1966)

Cytochrome P450 46A1 (CYP46A1) is a microsomal enzyme and cholesterol 24-hydroxylase that controls cholesterol elimination from the brain. This P450 is also a potential target for Alzheimer disease because it can be activated pharmacologically by some ...

5-Aminolevulinate synthase (ALAS; E.C. 2.3.1.37) is a pyridoxal 5′-phosphate (PLP)-dependent enzyme that catalyzes the key regulatory step of porphyrin biosynthesis in metazoa, fungi, and α-proteobacteria.

Allosteric enzymes as biosensors for molecular diagnosis [PDF]
Biosensors are hybrid analytical devices that amplify signals generated from the specific interaction between a receptor and the analyte, through a biochemical mechanism. Biosensors use tissues, whole cells, artificial membranes or cell components like proteins or nucleic acids as receptors, coupled to a physicochemical signal transducer.

Insights Into the Allosteric Inhibition of the SUMO E2 Enzyme Ubc9.
Conjugation of the small ubiquitin-like modifier (SUMO) to protein substrates is an important disease-associated posttranslational modification, although few inhibitors of this process are known.
