a, mass spectrometry (SELDI) profiles for the glycosylation of
MUC5AC-9 by hT10CD-derived constructs. The three peaks (0, 1, and
2) within the regions marked as the mono- and diglycosylated peptides
represent the naked, mono-, and di-sodiated species. hT10 with its native
lectin domain alone is able to transfer a GalNAc to the MUC5AC-9 peptide.
Deletion or substitution of its lectin domain leads to loss of this
activity.
