[NMR paper] Carbene footprinting reveals binding interfaces of a multimeric membrane spanning protein
Carbene footprinting reveals binding interfaces of a multimeric membrane spanning protein
Mapping the interaction sites between membrane spanning proteins is a key challenge in structural biology. In this study a carbene footprinting approach is developed and applied to identify the interfacial sites of a trimeric, integral membrane protein, OmpF, solubilised in micelles. The diazirine-based footprinting probe is effectively sequestered by, and incorporated into, the micelles leading to efficient labelling of the membrane-spanning regions of the protein upon irradiation at 349 nm. Areas...

[NMR paper] Laser-initiated Radical Trifluoromethylation of Peptides and Proteins and Its Application to Mass Spectrometry-Based Protein Footprinting
Laser-initiated Radical Trifluoromethylation of Peptides and Proteins and Its Application to Mass Spectrometry-Based Protein Footprinting
We describe a novel, laser-initiated radical trifluoromethylation for protein footprinting and establish its broad residue coverage. *CF3 reacts with 18 of 20 common amino acids including Gly, Ala, Ser, Thr, Asp, Glu that are relatively "silent" with *OH. This new approach to footprinting is a bridge between trifluoromethylation in materials and medicinal chemistry and structural biology and biotechnology. Its application to a membrane protein and to...
