he 1H NMR chemical shift for one of the two resonances attributed to H9 in Table 1 was incorrectly given as 3.46 ppm, but it is actually 3.68 ppm. Also in Table 1, the values given for the 13C chemical shifts of positions 1 and CH3CON should be switched: the 13C shift value for position 1 should be 176.09 ppm, while for CH3CON it should be 177.87 ppm. In the section on Sample Stability the MW of the oxoPSA was given as 30 kDa and should have been 20 kDa.
