A perspective on the discovery of enzyme activators

open access: yesSLAS Discovery, 2022
Enzyme activation remains a largely under-represented and poorly exploited area of drug discovery despite some key literature examples of the successful application of enzyme activators by various mechanisms and their importance in a wide range of ...

Spontaneous polarization and locomotion of an active particle with surface-mobile enzymes [PDF]

open access: yesPhys. Rev. Fluids 5, 122001 (2020), 2020
We examine a mechanism of locomotion of active particles whose surface is uniformly coated with mobile enzymes. The enzymes catalyze a reaction that drives phoretic flows but their homogeneous distribution forbids locomotion by symmetry. We find that the ability of the enzymes to migrate over the surface combined with self-phoresis can lead to a ...

Pró-fármaco ativado por enzima, uma estratégia promissora na quimioterapia

open access: yesQuímica Nova, 2006
Strategies that promote selective activation of prodrugs by enzymes can be divided into two major classes: 1) deliver of a monoclonal antibody-enzyme immunoconjugate that can recognize a specific antigen and promote the prodrug to a citotoxic drug, with ...

Unraveling the activation mechanism of the potato tuber ADP-glucose pyrophosphorylase. [PDF]

open access: yesPLoS ONE, 2013
ADP-glucose pyrophosphorylase regulates the synthesis of glycogen in bacteria and of starch in plants. The enzyme from plants is mainly activated by 3-phosphoglycerate and is a heterotetramer comprising two small and two large subunits.

Lectin Pathway Enzyme MASP-2 and Downstream Complement Activation in COVID-19

open access: yesJournal of Innate Immunity, 2022
Mannose-binding lectin-associated serine protease 2 (MASP-2) is the main activator of the lectin complement pathway and has been suggested to be involved in the pathophysiology of coronavirus disease 2019 (COVID-19).

Absolute diffusion measurements of active enzyme solutions by NMR [PDF]

open access: yes, 2018
The diffusion of enzymes is of fundamental importance for many biochemical processes. Enhanced or directed enzyme diffusion can alter the accessibility of substrates and the organization of enzymes within cells. Several studies based on fluorescence correlation spectroscopy (FCS) report enhanced diffusion of enzymes upon interaction with their ...

Determination of enzyme activities with the enzyme thermistor unit [PDF]

open access: yesFEBS Letters, 1979
Practically all enzyrnic reactions can be followed by calorimetry. Important advantages of this technique are that the optical properties of the sample do not interfere with the measurements and that no auxiliary enzymic reactions are required such as those leading to changes in optical absorption that can be followed spectrophotometrically.

Interactions between the endocrine and immune systems in locusts [PDF]

open access: yes, 2003
The prophenoloxidase cascade in the haemolymph of mature adult Locusta migratoria migratorioides (R & F) is activated in response to injection of laminarin, a -1,3 glucan.

A Theory of Enzyme Chemotaxis: Comparison Between Experiment and Model [PDF]

open access: yesBiochemistry, 2018, 57 (43), 6256, 2018
Enzymes show two distinct transport behaviors in the presence of their substrates in solution. First, their diffusivity enhances with increasing substrate concentration. In addition, enzymes perform directional motion toward regions with high substrate concentration, termed chemotaxis.

Expression and modulation of an NADPH oxidase in mammalian astrocytes [PDF]

open access: yes, 2005
Amyloid β peptides generate oxidative stress in hippocampal astrocytes through a mechanism sensitive to inhibitors of the NADPH oxidase [diphenylene iodonium (DPI) and apocynin].
