abstract = {Severe acute respiratory syndrome coronavirus is the
causative agent of a respiratory disease with a high case
fatality rate. During the formation of the coronaviral
replication/transcription complex, essential steps include
processing of the conserved polyprotein nsp7–10 region by
the main protease M$^{pro}$ and subsequent complex formation
of the released nsp's. Here, we analyzed processing of the
coronavirus nsp7–10 region using native mass spectrometry
showing consumption of substrate, rise and fall of
intermediate products and complexation. Importantly, there
is a clear order of cleavage efficiencies, which is
influenced by the polyprotein tertiary structure.
Furthermore, the predominant product is an nsp7+8(2 : 2)
hetero-tetramer with nsp8 scaffold. In conclusion, native
MS, opposed to other methods, can expose the processing
dynamics of viral polyproteins and the landscape of protein
interactions in one set of experiments. Thereby, new
insights into protein interactions, essential for generation
of viral progeny, were provided, with relevance for
development of antivirals.},
