Sequence alignment. The sequence alignment of avidin, avidin related proteins AVR2, AVR4 and AVR6 (Laitinen et al., 2002), translated AVR genes AVR-A, AVR-B and AVR-C from chicken genome database and putative biotin-binding proteins BBP-A and BBP-B. Numbering and secondary structures are according to avidin sequence. Completely conserved amino acids are shown in white with black background. Residues with direct contact to biotin in avidin (Livnah et al., 1993) are indicated with black triangles.
