In a system of purified components , binding of __NODE__ protein and promoter fragment ( 140 266 ) from __SP__ C __NODE__ [__NODE__] gene consisting of __NODE__ response element and a protein protein complex consisting of __NODE__ and of __NODE__ is greater than binding of __NODE__ protein and mutant promoter fragment ( 140 266 ) ( with its __NODE__ response element mutated ) from __SP__ C __NODE__ [__NODE__] gene and a protein protein complex consisting of __NODE__ and of __NODE__ .
