Abstract

The worldwide COVID-19 pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Nonstructural protein 3 (nsp3) has 1945 residues and is the largest protein encoded by SARS-CoV-2. It comprises more than a dozen independent domains with various functions. Many of these domains were studied in the closely-related virus SARS-CoV following an earlier outbreak. Nonetheless structural and functional information on the C-terminal region of nsp3 containing two transmembrane and three extra-membrane domains remains incomplete. This part of the protein appears to be involved in initiation of double membrane vesicle (DMV) formation, membranous organelles the virus builds to hide its replication-transcription complex from host immune defenses. Here we present the near-complete backbone and Ile, Leu, and Val methyl group chemical shift assignments of the most C-terminal domain of nsp3, CoV-Y. As the exact function and binding partners of CoV-Y remain unknown, our data provide a basis for future NMR studies of protein-protein interactions to elucidate the molecular mechanism of DMV formation.
