Critical to the use of solution NMR to describe the structure and flexibility of membrane proteins is the thorough understanding of the degree of perturbation induced by the detergent or other membrane mimetic. To develop a deeper understanding of the interaction between membrane proteins and micelles or bicelles, we will investigate the differences in structure and flexibility of a model membrane protein TM0026 from Thermotoga maritima using solution NMR. A comparison of the structural differences between TM0026 solubilized in different detergent combinations will provide important insight into the degree of modulation of membrane proteins by detergent physical properties. Here we report the nearly complete backbone and Cβ resonance assignments of the two transmembrane helical model protein TM0026. These assignments are the first step to using TM0026 to elucidate the interaction between membrane proteins and membrane mimetics.
