Phage-Induced Alignment of Membrane Proteins Enables the Measurement and Structural Analysis of Residual Dipolar Couplings with Dipolar Waves and lambda-Maps
At pH > 6 added filamentous bacteriophage fd is compatible with many of the detergents used to solubilize membrane proteins for solution NMR studies of membrane proteins and, therefore, serves as an alignment media. In combination with strained polyacrylamide get alignment, Dipolar Waves can be used to directly assess the secondary structure and a A-map extracts the order tensors for de novo structure calculation of membrane proteins without distance restraints.
