In Table 1, a factor of 10−4 was incorrectly inserted in front of the units h−1 and μm−1 h−1 for the apparent Kcat and Kcat/Km values. As a result, the reported values in Table 1 underrepresent the apparent Kcat values by a factor of 104. Our error does not affect the conclusions of the article. We apologize for any confusion that this error may have caused. The corrected Table 1 is shown below.
