The COVID-19 resource centre is hosted on Elsevier Connect, the company's public news and information website. Elsevier hereby grants permission to make all its COVID-19-related research that is available on the COVID-19 resource centre - including this research content - immediately available in PubMed Central and other publicly funded repositories, such as the WHO COVID database with rights for unrestricted research re-use and analyses in any form or by any means with acknowledgement of the original source. These permissions are granted for free by Elsevier for as long as the COVID-19 resource centre remains active.

Stereoview of the head-binding domain. The β-sheets A and B form the walls of a dome-like structure. (a) Side view perpendicular to the trimer axis. The side contacts between the subunits are not very extensive. (b) Top view. A cluster of the three Phe22 residues at the molecular triad stabilises the head-binding domain. (c) Bottom view. The N-terminal polypetide strands extend to the neighbouring subunits and shield the single Met89 from the solvent, which was replaced by Met(Te) for heavy atom derivative preparation. The Figure was produced with MOLSCRIPT (Kraulis, 1991).
