FIG 5.

Activity of AtzF (and fragments) at different pHs and temperatures. k_cat values at different pH levels obtained at 28°C (A) and 4°C (B) for AtzF, AtzF₄₆₇, and AtzF H488A were compared. All the data points plotted had standard errors of less than 5.3%, and standard errors are presented in Table S2 in the supplemental material.
