Chem. Commun., 2015, 51,195-197
DOI: 10.1039/C4CC06916A, CommunicationKhoi Tan Nguyen
Electronically enhanced chiral SFG spectroscopy was employed to study the lipid bound cyt c in situ. It was directly observed that upon interacting with anionic phospholipids, the amino acid residues around the heme adopted the [small beta]-sheet conformation. In addition, the orientation of this newly formed [small beta]-sheet structure was found to be sensitive to the bulk pH.
