Objective(S): Natural and artificial enzymes have shown important roles in biotechnological processes. Recently, design and synthesis of artificial enzymes especially peroxidase mimics has been interested by many researchers. Due to disadvantages of natural peroxidases, there is a desirable reason of current research interest in artificial peroxidase mimics. Metho...

During recent years, the possibility to create custom biocompatible nanoshapes using DNA as a building material has rapidly emerged. Further, these rationally designed DNA structures could be exploited in positioning pivotal molecules, such as enzymes, with nanometer-level precision. This feature could be used in the fabrication of artificial biochemical machinery that is able to mimic the comp...

Prior reduction of chicken liver xanthine dehydrogenase with xanthine or NADH leads to accelerated loss of enzymic FAD on exposure to 3 M KI. Reduction with NADH leads to the dissociation of all of the FAD, whereas reduction with xanthine results in the rapid dissociation of only 50% of the FAD. In both cases the xanthine ---f NAD activity is completely abolished. Oxidation of xanthine in the p...

Nicotinamide adenine dinucleotide (NAD) is an essential coenzyme for numerous biocatalytic pathways. While in nature, NAD+ continuously regenerated from NADH by enzymes, all synthetic regeneration strategies require a continuous supply of expensive reagents and generate byproducts, making these unattractive. In contrast, we present artificial enzyme combination that produces oxygen water contin...
