Summary of NMR and structural statisticsa for Salmonella SrfN, YahO, and SssB-I.

aStructural statistics were computed for ensembles of 20 deposited structures (PDB entries, SrfN: 2MA8, YahO: 2MA4, SssB-I: 2M2J2) using PSVS 1.4 [51], except as noted otherwise.bComputed the expected number of typically observed resonance peaks, excluding: highly exchangeable protons (N-terminal, Lys, and Arg amino groups, hydroxyls of Ser, Thr, Tyr), carbonyl carbons of Asp, Glu, Asn, and Gln side chains, non-protonated aromatic carbons, and the C-terminal His6 tag.cAverage distance violations were calculated using the sum over r−6.dOrdered residue ranges [S(phi)+S(psi) >1.8] : SrfN:23–45,49–92; YahO: 23–45,49–73,84–90; SssB-I: 23–43,48–75,81–90.eAll (excluding tags) residue ranges: SrfN: 22–96; YahO: 22–91; SssB-I: 22–91.
