MS/MS analysis for amino acid sequence of the peptides of α-GalNAcase I and II. The individually obtained peptide fraction from RP-HPLC were subjected to MS/MS fragmentation. Amino acid sequences of peptides were determined from the fragmentation pattern by Bruker Data Analysis software (version 4.0). a, Peptide 17 of enzyme I; b, peptide 15 of enzyme I; c, peptide 13 of enzyme II; d peptide 16 of enzyme II
