FIG. 1.

Sequence homologies in OmpA-like regions. Amino acid sequences (44 residues) of the distinctive OmpA-like regions of 18 proteins belonging to the OmpA family were compared to the homologous region (residues 258 to 301) near the C terminus of the predicted sequence of the gene specifying OmpATb of M. tuberculosis, using the program PileUp from the GCG suite. The left-hand column lists the SwissProt accession numbers for the proteins compared. Amino acids in boldfaced type are shared with OmpATb; residues underlined in the mycobacterial sequence are conserved throughout the series of sequences. Dots indicate gaps introduced by the program to maximize matching.
