Article Title: Native dynamics and allosteric responses in PTP1B probed by high‐resolution HDX‐MS

doi: 10.1002/pro.5024

Figure Lengend Snippet: High‐resolution local HDX‐MS map for apo PTP1B. (a) Woods plot of HDX rates for 312 peptides of apo PTP1B showing %deuteration at 30 s of labeling for each peptide. (b) Deconvoluted HDX rates at 30 s of labeling time mapped to a crystal structure of the PTP1B catalytic domain in the closed state (PDB ID 1SUG). Several key loops and the α4 helix (residues 187–200) and α7 helix (residues 285–298) are indicated.

Article Snippet: Peptic peptides were eluted through a C18 analytical column (Hypersil Gold, 50 mm length × 1 mm diameter, 1.9 μm particle size, Thermo Fisher Scientific) into a Bruker maXis‐II ESI‐QqTOF high‐resolution mass spectrometer.
