Azurin-poly(N-isopropylacrylamide) conjugates by site-directed mutagenesis and their thermosensitive behavior in electron-transfer processes.

Searching for "intelligence": Azurin-PNIPAM conjugates were prepared by site-directed mutagenesis followed by protein reconstitution by using imidazole-conjugated poly(N-isopropylacrylamides). The polymer-bound imidazole acts as a ligand in the active site of the blue copper protein azurin. The bioconjugates showed thermosensitive behavior in electron-transfer processes with reduced cytochrome c.
