Deconvoluted MS spectra show that peptide GNLSTAADVTDK from AtaC is modified with a hexose polymer ranging from 1 to 28 units. (b) MS/MS spectrum of m/z 758.3497(+2), corresponding to GNLSTAADVTDK modified with two hexoses, showed continuous fragmentation ions, which confirm the peptide identity. The hash tag marks doubly charged ion with neutral loss of hexose from precursor ion. y’ indicates the y ion without hexoses.
