Page 43670: In the right column, 15 lines from the
bottom, the words "poor" and "better" should be interchanged.
The correct sentences should read: "From Fig. 4a, it seems
that, for the E175A acid-base mutant, with substrates bearing better
leaving groups (pKa < 6), the rate-limiting step is
also the deglycosylation step. However, for substrates with poor
leaving group ability (higher pKa), a much greater
dependence of the kcat values on the leaving group
ability of the substrate was observed, with a
1g value of
0.9."
