(A) and (B) Expanded regions of the two-dimensional {1H, 15N} HSQC spectra of delipidated ApolPBP1ΔP129-V142 (0.3 mM) in 50 mM sodium phosphate buffer, containing 5% D2O, 1 mM EDTA, and 0.01% sodium azide, showing movements of certain peaks as a result of pH. The pH of the buffer is indicated on the spectra. (C) Residues that undergo moderate-to-large change in their chemical shift positions as a result of change in pH are shown as red spheres in the three-dimensional structure of ApolPBP1 (PDB id 1QWV). The C-terminus tail (residues 131–142) is colored magenta. The three-dimensional structure representation was prepared using PyMOL molecular graphics system.
