Figure 4From: The major secreted protein Msp1/p75 is O-glycosylated in Lactobacillus rhamnosus GGTandem mass spectrometry of the proteinase K-generated peptide T 101 VETPSSA 108 carrying two hexoses. The MS/MS spectrum of m/z 1115.9 [M+H]+ was acquired by graphitized carbon nano. The Ser-Ser motif which was found to be substituted by hexoses is highlighted in blue. Filled circle indicates hexose.Back to article page
