Complexation of ruthenium with glucose oxidase modified by 4- pyridineacetic and 4-imidazoleacetic acids
Abstract
Glucose oxidase (GO) conjugated with 4-pyridineacetic and 4- imidazoleacetic acids reacted with cis- [Ru(bpy)2Cl2] to afford the Ru-containing catalytically active species Ru–X–GO (X = pyridine or imidazole) capable of the intramolecular electron transfer from reduced FAD to an electrochemically generated RuIII centre.
