A recombinant protein, including: (a) alpha subunit of an FAD-GDH; and (b) a minimal cytochrome c peptide is provided. Additionally, an electrode coupled to a recombinant protein, the recombinant protein made of: (a) a cofactor of a redox enzyme; (b) a redox enzyme; (c) a linker moiety configured to link any one of: the cofactor or the enzyme to an electron transfer (ET) domain; and (d) an ET domain, is also provided. Methods for: (a) transferring an electron to an electrode, by coupling the recombinant protein an electrode; and (b) quantifying the amount of an analyte e.g., glucose are also provided.
