Summary During the past decade numerous advances have been made in understanding the structure, mechanism and clinical properties of dihydropteridine reductase. An attempt is made here to delineate the current status of this essential enzyme by describing its structural features, its kinetic mechanism, the cloning and expression of both rat and human ...

A unique cytochrome P450 (CYP) oxidoreductase (CPR) sustains activities of human microsomal CYPs. Its function requires toggling between a closed conformation enabling electron transfers from NADPH to FAD and then FMN cofactors and open conformations ...

Phytophthora capsici sterol reductase PcDHCR7 has a role in mycelium development and pathogenicity
The de novo biosynthesis of sterols is critical for the majority of eukaryotes; however, some organisms lack this pathway, including most oomycetes. Phytophthora spp.

Chromium bioremediation by Alcaligenes sp. strain newly isolated from chromite mine of Sabzevar [PDF]
In this work, CKCr-6A strain was found to be highly resistant to some toxic heavy metals such as Cr+6, Cr+3, Cu+2, Co+2, Cd+2, Pb+2, Hg+2, U+6, tellurium, and selenite. Herein, high chromate tolerance of an isolated strain is reported with a high minimum

Thiol Reductases in Deinococcus Bacteria and Roles in Stress Tolerance
Deinococcus species possess remarkable tolerance to extreme environmental conditions that generate oxidative damage to macromolecules. Among enzymes fulfilling key functions in metabolism regulation and stress responses, thiol reductases (TRs) harbour ...

Human Carbonyl Reductase 1 Is an S-Nitrosoglutathione Reductase [PDF]
Human carbonyl reductase 1 (hCBR1) is an NADPH-dependent short chain dehydrogenase/reductase with broad substrate specificity and is thought to be responsible for the in vivo reduction of quinones, prostaglandins, and other carbonyl-containing compounds including xenobiotics.

Identifying structural and dynamic changes during the Biliverdin Reductase B catalytic cycle
Biliverdin Reductase B (BLVRB) is an NADPH-dependent reductase that catalyzes the reduction of multiple substrates and is therefore considered a critical cellular redox regulator.

Ketopantoyl lactone reductase is a conjugated polyketone reductase [PDF]
Ketopantoyl lactone reductase (EC 1.1.1.168) of Saccharomyces cerevisiae was found to catalyze the reduction of a variety of natural and unnatural conjugated polyketone compounds and quinones, such as isatin, ninhydrin, camphorquinone and beta-naphthoquinone in the presence of NADPH. 5-Bromoisatin is the best substrate for the enzyme (Km = 3.1 mM; Vmax
