Urate oxidase, or uricase (EC 1.7.3.3), is a peroxisomal enzyme that catalyzes the oxidation of uric acid to allantoin in most mammals. In humans and certain other primates, however, the enzyme has been lost by some unknown mechanism. To identify the molecular basis for this loss, urate oxidase cDNA clones were isolated from pig, mouse, and baboon, and their DNA sequences were determined. The m...

Aquatic organisms present, not only simple sources of accumulated metal, but can interact with metals, altering their toxicity. Due to exposition of biosphere with metals, organisms have developed various defense mechanisms to protect themselves against adverse effects of these ions and their compounds. Metallothionein (MT) is one of that which represents a critical mechanism for detoxification...

Nanoparticles (NPs) have been widely used in medical and therapeuticapplications. However, their albumin binding and their cytotoxicity assays havenot been well explored. In his study, the interaction of NiO NPs with human serumalbumin (HSA) was explored by circular dichroism (CD) study, molecular dockingand dynamic studies. Afterwards the cytotoxicity of NiO NPs against...
