FIG 6.

Comparison of the activities of PBL5X and the WT. (A) Temperature dependence of the specific activities of the WT and PBL5X. The caseinolytic activities of the enzymes were determined at the indicated temperatures in buffer A. The values are means ± standard deviations (bars) of the results of three independent experiments. (B) Ratio of the specific activities of PBL5X and the WT. The activity of PBL5X relative to that of the WT was calculated, with that of WT at the respective temperatures defined as 1.
