additional information the enzyme interacts with redox mediators, e.g. 9,10-phenantroline-5,6-dione, 9,10-phenanthrenequinone, N-methylphenazonium methyl sulfate, ferrocene, ferrocenecarboxylic acid, alpha-methylferrocenemethanol, ferrocenecarboxaldehyde. 9,10-phenantroline-5,6-dione and 9,10-phenanthrenequinone are the best redox mediators or electron acceptors for this type of GOx. The redox mediators in a reaction mixture containing glucose, GOx and 1,4-benzoquinone lead to a 1.4-7.9fold rise of the 1,4-benzoquinone reduction rate, method evaluation Talaromyces funiculosus

Protein Variants

Protein Variants Comment Organism
additional information construction of a Penicillium funiculosum highly active strain 46.1 from parental strain BIM F-15 as a producer of extracellular GOx by induced mutagenesis technique. The GOx from Penicillium funiculosum strain 46.1 differs from GOx purified from the parent strain BIM F-15 by reduced Michaelis constant, higher efficiency of glucose oxidation, pH dependence, and thermal stability, but it has similar thermal optimum. The enzyme-encoding gene has no special mutation Talaromyces funiculosus
