A) 15% PAGE followed by western blot analysis of Y33G at different SDS concentrations. Each lane represents separate gels with different concentrations of the denaturing agent. The SDS/enzyme molar ratios in the individual lanes were as follows: lane 1, 70; lane 2, 120; lane 3, 300. St, Bio-Rad low molecular weight standard.
B) Percentage of enzymatic activity of wild-type CDA (●) andY33G mutant CDA (■) after incubations with SDS concentrations ranging from 0.35 to 1.73 mM in order to give different SDS/enzyme molar ratios. The data of wild type CDA are from [20].
