Structures of mouse DUOX1-DUOXA1 provide mechanistic insights into enzyme activation and regulation. [PDF]

open access: yesNat Struct Mol Biol, 2020
DUOX1, an NADPH oxidase family member, catalyzes the production of hydrogen peroxide. DUOX1 is expressed in various tissues, including the thyroid and respiratory tract, and plays a crucial role in processes such as thyroid hormone biosynthesis and ...

Enzyme activation through the utilization of intrinsic dianion binding energy. [PDF]

open access: yesProtein Eng Des Sel, 2017
43 We consider 'the proposition that the intrinsic binding energy that results from the noncovalent interaction of a specific substrate with the active site of the enzyme is considerably larger than is generally believed.

Relief of autoinhibition by conformational switch explains enzyme activation by a catalytically dead paralog. [PDF]

open access: yesElife, 2016
Catalytically inactive enzyme paralogs occur in many genomes. Some regulate their active counterparts but the structural principles of this regulation remain largely unknown.

Protein Stabilization and Enzyme Activation in Ionic Liquids: Specific Ion Effects. [PDF]

open access: yesJ Chem Technol Biotechnol, 2016
There are still debates on whether the hydration of ions perturbs the water structure, and what is the degree of such disturbance; therefore, the origin of Hofmeister effect on protein stabilization continues being questioned.

Mathematical modelling of OAS2 activation by dsRNA and effects of dsRNA lengths

open access: yesAIMS Mathematics, 2021
The activation of 2'-5'-oligoadenylate synthetase (OAS) enzymes by direct interaction with viral double-stranded RNA (dsRNA) is a key part of the innate immune response to viral infection.

Conditionally Activated (“Caged”) Oligonucleotides

open access: yesMolecules, 2021
Conditionally activated (“caged”) oligonucleotides provide useful spatiotemporal control for studying dynamic biological processes, e.g., regulating in vivo gene expression or probing specific oligonucleotide targets.

Cyclic nucleotide specificity of the activator and catalytic sites of a cGMP-stimulated cGMP phosphodiesterase from Dictyostelium discoideum [PDF]

open access: yes, 1985
The cellular slime mold Dictyostelium discoideum has an intracellular phosphodiesterase which specifically hydrolyzes cGMP. The enzyme is activated by low cGMP concentrations, and is involved in the reduction of chemoattractant-mediated elevations of ...

Iron-Dependent Trafficking of 5-Lipoxygenase and Impact on Human Macrophage Activation

open access: yesFrontiers in Immunology, 2019
5-lipoxygenase (5-LOX) is a non-heme iron-containing dioxygenase expressed in immune cells that catalyzes the two initial steps in the biosynthesis of leukotrienes.
