Alignment of the amino acid sequence stretches
corresponding to subdomains I, II, and III of GNA with those of
Marpola-1 (I′, II′, and III′) and Marpola-3 (I′′, II′′, and
III′′). The conserved amino acid residues forming the Man-binding sites
of GNA and the corresponding residues of the liverwort lectins are in
bold. The conserved Val residue participating to the Man-binding sites
of GNA is in bold and is underlined.
