Food Safety and Health, EarlyView.Psidium guajava leaves contain potent bioactive compounds like quercetin, myricetin, and triterpenoids that show antioxidant, antidiabetic, anti‐inflammatory, and anticancer effects. They act by modulating NF‐κB, PPARγ, and α‐glucosidase and by inducing apoptosis and cell cycle arrest.

Carbonyl reductase (secondary-alcohol:NADP(+) oxidoreductase, EC 1.1. 1.184) belongs to the family of short chain dehydrogenases/reductases (SDR). Carbonyl reductases (CBRs) are NADPH-dependent, mostly monomeric, cytosolic enzymes with broad substrate specificity for many endogenous and xenobiotic carbonyl compounds.

Ribonucleotide reductases (RNRs) transform RNA building blocks to DNA building blocks by catalyzing the substitution of the 2′OH-group of a ribonucleotide with a hydrogen by a mechanism involving protein radicals. Three classes of RNRs employ different mechanisms for the generation of the protein radical. Recent structural studies of members from each

Ferric reductases or flavin reductases?
Biometals, 1994Assimilation of iron by microorganisms requires the presence of ferric reductases which participate in the mobilization of iron from ferrisiderophores. The common structural and catalytic properties of these enzymes are described and shown to be identical to those of flavin reductases.

Evidently, considerable rearrangement of charge driven by reduction significantly raises the effective dielectric. It seems likely that centres S-2 and FR-2 are apparently low-potential clusters merely
