Unraveling the role of protein dynamics in dihydrofolate reductase catalysis [PDF]

, 2013
Protein dynamics have controversially been proposed to be at the heart of enzyme catalysis, but identification and analysis of dynamical effects in enzyme-catalyzed reactions have proved very challenging.

Xanthatin‐13‐(Pyrrolidine‐2‐Carboxylic Acid), a Sesquiterpene Lactone Isolated From Burdock Leaf, Attenuated Aβ25‐35 Toxicity and Memory Deficits in a Pharmacological Mouse Model of Alzheimer's Disease

Phytotherapy Research, Volume 40, Issue 5, Page 2824-2843, May 2026.
ABSTRACT Alzheimer's disease (AD) is a severe form of dementia, which occurrence increases with age and lifestyle conditions. It is characterized by amyloid protein accumulation forming senile plaques, hyperphosphorylated tau protein forming neurofibrillary tangles, neuroinflammation, and oxidative stress, leading to synapse loss and cell death ...

Anti‐inflammatory effects of physical stimuli: The central role of networks in shaping the future of pharmacological research

British Journal of Pharmacology, Volume 183, Issue 10, Page 2177-2196, May 2026.
Addressing complexity in the study of life sciences through Systems Biology and Systems Medicine has been transformative, making Systems Pharmacology the next logical step. In this review, we focus on physical stimuli, whose potential in pharmacology has been neglected, despite demonstrated therapeutic properties.

Unveiling the Connection: Viral Infections and Genes in dNTP Metabolism

Viruses
Deoxynucleoside triphosphates (dNTPs) are crucial for the replication and maintenance of genomic information within cells. The balance of the dNTP pool involves several cellular enzymes, including dihydrofolate reductase (DHFR), ribonucleotide reductase (

Soluble oligomerization provides a beneficial fitness effect on destabilizing mutations

, 2012
Mutations create the genetic diversity on which selective pressures can act, yet also create structural instability in proteins. How, then, is it possible for organisms to ameliorate mutation-induced perturbations of protein stability while maintaining ...

Dihydrofolate reductase as a model for studies of enzyme dynamics and catalysis [version 1; referees: 2 approved]

F1000Research, 2015
Dihydrofolate reductase from Escherichia coli (ecDHFR) serves as a model system for investigating the role of protein dynamics in enzyme catalysis. We discuss calculations predicting a network of dynamic motions that is coupled to the chemical step ...
