Characteristics of Csd and Fem protein in A. florea. (a) The aligned conceptual translation of the hypervariable region (HVR) between seven pairs of functionally different csd alleles of females is shown. The HVR encodes a succession of asparagine residues (N) and single serine residues (S). (b) Deduced amino acid sequence encoding the region of the predicted coiled-coil motif, framed in black. For A. mellifera, A. cerana and A. dorsata csd, the prediction is based on the six amino acids in gray shaded boxes. A. florea differs in one position compared to the other species and does not form a coiled-coil motif (unframed). The homologous region for fem is placed below for comparison, with the corresponding amino acids marked. (c) Deduced amino acid sequence encoding the region of the predicted N-terminal coiled-coil motif for A. florea framed in black. Only one amino acid change and a two amino acid difference shown as a gap (shaded boxes) seem sufficient for the formation in Csd and Fem in A. florea, whereas this is not found in the other Apis species (unframed).
