Thioredoxin reductase [PDF]

open access: yesBiochemical Journal, 2000
The mammalian thioredoxin reductases (TrxRs) are a family of selenium-containing pyridine nucleotide-disulphide oxidoreductases with mechanistic and sequence identity, including a conserved -Cys-Val-Asn-Val-Gly-Cys- redox catalytic site, to glutathione reductases.

Ketopantoyl lactone reductase is a conjugated polyketone reductase [PDF]

open access: yesFEMS Microbiology Letters, 1989
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

Thiol Reductases in Deinococcus Bacteria and Roles in Stress Tolerance

open access: yesAntioxidants, 2022
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]

open access: yesJournal of Biological Chemistry, 2008
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.

Mitochondrial Thioredoxin System as a Modulator of Cyclophilin D Redox State [PDF]

open access: yes, 2016
The mitochondrial thioredoxin system (NADPH, thioredoxin reductase, thioredoxin) is a major redox regulator. Here we have investigated the redox correlation between this system and the mitochondrial enzyme cyclophilin D.

Quinone Reductase 2 Is a Catechol Quinone Reductase [PDF]

open access: yesJournal of Biological Chemistry, 2008
The functions of quinone reductase 2 have eluded researchers for decades even though a genetic polymorphism is associated with various neurological disorders. Employing enzymatic studies using adrenochrome as a substrate, we show that quinone reductase 2 is specific for the reduction of adrenochrome, whereas quinone reductase 1 shows no activity.

Nitrogenase Fe Protein: A Multi-Tasking Player in Substrate Reduction and Metallocluster Assembly

open access: yesMolecules, 2022
The Fe protein of nitrogenase plays multiple roles in substrate reduction and metallocluster assembly. Best known for its function to transfer electrons to its catalytic partner during nitrogenase catalysis, the Fe protein is also a key player in the ...

Functional and Biogenetical Heterogeneity of the Inner Membrane of Rat-Liver Mitochondria [PDF]

open access: yes, 1971
Rat liver mitochondria were fragmented by a combined technique of swelling, shrinking, and sonication. Fragments of inner membrane were separated by density gradient centrifugation.

A hidden cause of infertility in hypothyroid patients [PDF]

open access: yes, 2020
Methylene tetrahydrofolate reductase (MTHFR) gene mutations could be the cause of infertility in hypothyroid patients. Hence, it is worthy to screen for MTHFR gene mutations in infertile hypothyroid females and their partners if infertility persists ...

Regulatory Roles of Six-Transmembrane Epithelial Antigen of the Prostate Family Members in the Occurrence and Development of Malignant Tumors

open access: yesFrontiers in Cell and Developmental Biology, 2021
The human six-transmembrane epithelial antigen of the prostate (STEAP) proteins, which include STEAP1–4 and atypical STEAP1B, contain six transmembrane domains and are located in the cell membrane.
