Oxidative Stress: Concept and Some Practical Aspects
Antioxidants, 2020 Oxidative stress is defined as “an imbalance between oxidants and antioxidants in favor of the oxidants, leading to a disruption of redox signaling and control and/or molecular damage”. This Commentary presents basic features of this global concept which

Studies on the relation between heme and nucleic acid syntheses in erythroid cell. II. Nucleic acid synthesis in erythroblast of anemic rat treated with aminopterin and bromouracil [PDF]
, 1968 With the bone marrow of anemic rats, which had received the repeated injections of phenylhydrazine once a day for three to four days, the effects of aminopterin and bromouracil on the nucleic acid metabolism of erythroblasts were observed in vivo ...

Distribution of enzymes cleaving pyridine nucleotides in animal tissues [PDF]
, 1957 A number of enzymes capable of splitting the pyridine nucleotides have been found in animal tissues. A portion of the DPNase (1) that hydrolyzes the nicotinamide ribose bond of DPN and TPN was reported in the microsomes of rat liver (1).

The Human SLC25A33 and SLC25A36 Genes of Solute Carrier Family 25 Encode Two Mitochondrial Pyrimidine Nucleotide Transporters [PDF]
, 2014 The human genome encodes 53 members of the solute carrier family 25 (SLC25), also called the mitochondrial carrier family, many of which have been shown to transport inorganic anions, amino acids, carboxylates, nucleotides, and coenzymes across the inner

Advanced Synthesis &Catalysis, EarlyView.We show how engineered ancestral amide bond synthetases (ABSs) together with cofactor recycling using a single polyphosphate kinase paves the way for chemoenzymatic synthesis of pharmacophores. The figure illustrates how ancestral ABS has a more flexible C‐terminal domain, which is associated with enhanced catalytic performance and expanded amine scope.
