Comments P.109 left column top paragraph: "These results, included in Table 1, are in accord with those of Sherman et al., except for the particular case of S16 that has valine in position 2 (ref 25). (They observed methionine loss for all cases in which the second residue was valine.) Several other posttranslational modifications, including methylation, acetylation, fragmentation, and amino acid side-chain derivatization, are listed in Table 1." All of them are different with three exceptions: one protein is found in both subunits (S20 and L26)
