... 85% inhibition of BHLmL2 and BHAb, respectively, while 1 mm 2-mer-captoethanol caused 85% and 97% inhibition of BHLmL2 and BHAb, respectively.The influence of pH on the activities of the BHenzymes ... 55% and 51%loss of the initial activities of BHLmL2 and BHAb,respectively. These results strongly suggest that Ser isinvolved in the catalytic activity of BHLmL2 and BHAb and are consistent ... 6 and Fig. 4, the Hill equation provided an excellent fit, withcoefficients of determination of 0.992 for BHLmL2 and 0.997 for BHAb. In addition, the fits of theV = f(S) curves were sigmoidal and...
