Post-translational modificationi

Heavily glycosylated with beta-arabinose on hydroxyprolines and with alpha-galactose on serines of the extensin-like domain. As no other sugars could be detected in the native lectin, it is unlikely that the three putative N-glycosylation sites are actually glycosylated.1 Publication
The N-terminus is blocked. The N-terminal sequences proposed in PubMed:9022287 and PubMed:11056399 originate probably from truncated proteins.
