However, some rare antibodies that target the SARS-CoV-2 NTD potently neutralize the virus. This finding suggests the NTD may contribute, in part, to protective immunity. Pansarbecovirus antibodies are desirable for broad protection, but the NTD region of SARS-CoV and SARS-CoV-2 exhibit a high level of sequence divergence; therefore, cross-reactive NTD-specific antibodies are unexpected, and there is no structure of a SARS-CoV NTD-specific antibody in complex with NTD. Here, we report a monoclonal antibody COV1-65, encoded by the IGHV1-69 gene, that recognizes the NTD of SARS-CoV S protein. A prophylaxis study showed the mAb COV1-65 prevented disease when administered before SARS-CoV challenge of BALB/c mice, an effect that requires intact fragment crystallizable region (Fc) effector functions for optimal protection in vivo. The footprint on the S protein of COV1-65 is near to functional components of the S2 fusion machinery, and the selection of COV1-65 escape mutant viruses identified critical residues Y886H and Q974H, which likely affect the epitope through allosteric effects. Structural features of the mAb COV1-65-SARS-CoV antigen interaction suggest critical antigenic determinants that should be considered in the rational design of sarbecovirus vaccine candidates.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
