Abstract

Investigation of the structure, assembly and function of protein-nucleic acid macromolecular machines requires multidimensional molecular and structural biology approaches. We describe modifications to an Orbitrap mass spectrometer, enabling high-resolution native MS analysis of 0.8-to 2.3-MDa prokaryotic 30S, 50S and 70S ribosome particles and the 9-MDa Flock House virus. The instrument's improved mass range and sensitivity readily exposes unexpected binding of the ribosome-associated protein SRA.
