^aFractional side-chain accessible surface area (asa) (fractional) of MotB residues that are conserved in OmpA-like PG-binding proteins.

Residue numbering is as in H. pylori MotB-C/periplasmic domain of Salmonella MotB. aAsa values for H. pylori MotB-C were averaged over all subunits in the asymmetric units of Form A and Form B crystals. The average values for the Salmonella MotB domain were calculated using the coordinates for the high-resolution crystal form (Research Collaboration for Structural Bioinformatics (RCSB) Protein Data Bank code 2zvy [7]).
