^a Mascot scores are indicated for the different samples; nd, not detected. ^bMolecular masses and pI values were calculated for the predicted fully processed enzymes. For the OmpA-like proteins the molecular masses and pI values were calculated for the C-terminal 111 amino acid residues representing the putative peptidoglycan-binding domain. The corresponding values for the full-length proteins are 36.6 kDa and pI = 4.6 for OmpA-like protein 1, and 36.6 kDa and pI = 4.7 for the OmpA-like protein 2.
