Figure 1

Trimeric state of the PhoSL peptide as revealed by gel filtration and chemical cross-linking analyses. Shown are (A) elution profile and (B) relation between elution volume and molecular mass of the proteins in gel filtration analysis, (C) SDS-PAGE gel after the cross-linking reaction with EDC and NHS, and (D) mass spectra of the three respective bands in (C). Asterisk in (A) shows the peak for the presumable hexamer of PhoSL.
