FIG. 4.

Alignment of TibA and pertactin precursor carboxy termini. Alignment of the C terminus of TibA (residues 791 to 989) and pertactin precursor (residues 712 to 910) was performed by using Clustalx software. A vertical line indicates positions with identical residues. A colon indicates that one of the following “strong” groups is fully conserved: STA, NEQK, NHQK, NDEQ, QHRK, MILV, MILF, HY, or FYW. A period indicates that one of the following “weaker” groups is fully conserved: CSA, ATV, SAG, STNK, STPA, SGND, SNDEQK, NDEQHK, NEQHRK, FVLIM, or HFY.
