Fig 3. Schematic comparison of BabA, BabB, and BabC.

Fig 3

The representative structures of BabA and BabB are based on the J99 amino acid sequence, whereas the structure of BabC is based on the consensus sequence defined in this study. The N-HR indicates N-terminal homology region, M-VR indicates middle variable region, which is characterized by sequence difference among the three Bab proteins. Note that the M-VR is conserved for each of the Bab proteins. The C-HR indicates C-terminal homologous region that shows >90% identity. The CT-R present at the N-terminus of BabB refers to the CT repeat region. VR-1 and VR-2 in BabC indicate regions of variability among the BabC amino acid sequences analyzed in this study (n = 15).
