Allosteric Regulation of Chromatin-Modifying Enzymes
Biochemistry, 2018Dynamic changes in chromatin structure are crucial for diverse biological processes. Given the complexity of the epigenetic landscape, understanding the specificity of chromatin modification has been a major interest in the epigenetics field. Recent progress in biochemical and structural analyses in the field of chromatin biology has revealed that ...

Allosteric regulation of purine nucleoside phosphorylase
Archives of Biochemistry and Biophysics, 1991Purine nucleoside phosphorylase (EC 2.4.2.1) from bovine spleen is allosterically regulated. With the substrate inosine the enzyme displayed complex kinetics: positive cooperativity vs inosine when this substrate was close to physiological concentrations, negative cooperativity at inosine concentrations greater than 60 microM, and substrate inhibition ...

Allosteric regulation, cooperativity, and biochemical oscillations
Biophysical Chemistry, 1990Allosteric regulation is associated with a number of periodic phenomena in biochemical systems. The cooperative nature of such regulatory interactions provides a source of nonlinearity that favors oscillatory behavior. We assess the role of cooperativity in the onset of biochemical oscillations by analyzing two specific examples.

Design of Allosterically Regulated Protein Catalysts
Biochemistry, 2015Activity of allosteric protein catalysts is regulated by an external stimulus, such as protein or small molecule binding, light activation, pH change, etc., at a location away from the active site of the enzyme. Since its original introduction in 1961, the concept of allosteric regulation has undergone substantial expansion, and many, if not most ...

An Allosterically Regulated, Four-State Macrocycle
Inorganic Chemistry, 2018Macrocycles capable of host-guest chemistry are an important class of structures that have attracted considerable attention because of their utility in chemical separations, analyte sensing, signal amplification, and drug delivery. The deliberate design and synthesis of such structures are rate-limiting steps in utilizing them for such applications ...

Dynamic Protein Allosteric Regulation and Disease
2019Allostery is largely associated with conformational and functional transitions in individual proteins. All dynamic proteins are allosteric. This concept can be extended to consider the impact of conformational perturbations on cellular function and disease states.

Engineering Allosteric Regulation into Biological Catalysts
ChemBioChem, 2009AbstractEnzymes and ribozymes constitute two classes of biological catalysts. The activity of many natural enzymes is regulated by the binding of ligands that have different structures than their substrates; these ligands are consequently called allosteric effectors.

Neuroleptics — Allosteric Tyrosine Hydroxylase Regulators
1986The action of psychotropic compounds on catecholaminergic processes is a key factor in their action on the function of the central and peripheral nervous system (Zakusov, 1973; Valdman et al., 1979; Breese et al., 1978; Bunney and Aghajanian, 1975), since impairment of these processes may be an important stage in the onset and development of ...
