AGP31 structural models. The different domains of the mature AGP31 are represented from left to right: N-terminal AGP motif (AGP), His stretch (His), Pro-rich domain (Pro-rich), and C-terminal PAC domain (PAC). The various glycoforms and truncated forms of AGP31 are schematized, as well as the results obtained for isolating, detecting, and analyzing each of them using the different approaches carried out in this study. The limits encountered at each step are indicated. AG motifs assumed to substitute the short N-terminal AGP motif are indicated. The size-heterogeneous Hyp-O-Gal/Ara-rich motifs expected on the Pro-rich domain are represented with green lines, and putative short Ara-oligosaccharides are represented with purple lines.
