Lineweaver-Burk plots. Lineweaver-Burk plot of the reaction catalyzed by the β-galactosidase hybrid between K. lactis and A. niger (red circles) and the native β-galactosidase of K. lactis (square blue) in the presence of the synthetic substrate ONPG (A) or the natural substrate lactose (B). Experimental variations are less than 10% of the value of the point. Results are the average of two independent experiments.
