Characterizing N-Glycosylation of Pilins and Flagellins from Haloferax volcanii


ABSTRACT: Mass spectrometric analysis of cesium chloride purified flagellins and pilins confirmed previously identified N-glycopeptides for FlgA1, revealed additional N-glycopeptides for FlgA1 and FlgA2 and characterized N-glycosylation of PilA1 and PilA2. Analyses were performed using different MS methods (with and withoout applying IS-CID) for samples from wildtype as well as aglB knockout strains.

N-Glycosylation is a post-translational modification common to all three domains of life. In many archaea, the oligosacharyltransferase (AglB)-dependent N-glycosylation of flagellins is required for flagella assembly. However, whether N-glycosylation is required for the assembly and/or function of the structurally related archaeal type IV pili is unknown. Here, we show that of six Haloferax volcanii adhesion pilins, PilA1 and PilA2, the most abundant pilins in pili of wild-type and ΔaglB strains  ...[more]
