Figure 1. Predicted amino acid sequence of the honeybee transferrin AmTRF. Residues conserved in the honeybee protein (Apis mellifera) and in two insect transferrins from the cockroach (Balberus discoidalis) and the termite (Mastotermes darwiniensis) are boxed and shaded in yellow. The leader peptide is typed in blue and the conserved amino acids implicated in iron binding are typed in red. GenBank accession No. Am: AY217097, Bd: AAA27820, Md: AAN03488.
