Computational Development of Inhibitors of Plasmid-Borne Bacterial Dihydrofolate Reductase [PDF]

Antibiotics, 2022
Resistance to trimethoprim and other antibiotics targeting dihydrofolate reductase may arise in bacteria harboring an atypical, plasmid-encoded, homotetrameric dihydrofolate reductase, called R67 DHFR. Although developing inhibitors to this enzyme may be

Oxidative degradation of dihydrofolate reductase increases CD38-mediated ferroptosis susceptibility [PDF]

Cell Death and Disease, 2022
High expression of CD38 in tissues is a characteristic of aging, resulting in a decline in nicotinamide adenine dinucleotide (NAD) and increasing cellular reactive oxygen species (ROS).

Dihydrofolate Reductase Is a Valid Target for Antifungal Development in the Human Pathogen Candida albicans

mSphere, 2020
While the folate biosynthetic pathway has provided a rich source of antibacterial, antiprotozoal, and anticancer therapies, it has not yet been exploited to develop uniquely antifungal agents.

Tales of Dihydrofolate Binding to R67 Dihydrofolate Reductase

Biochemistry, 2015
Homotetrameric R67 dihydrofolate reductase possesses 222 symmetry and a single active site pore. This situation results in a promiscuous binding site that accommodates either the substrate, dihydrofolate (DHF), or the cofactor, NADPH. NADPH interacts more directly with the protein as it is larger than the substrate.
