Crystal structure of the Mengla virus VP30 C-terminal domain
The family Filoviridae contains many important human viruses, including Marburg virus (MARV) and Ebola virus (EBOV). Mengla virus (MLAV), a newly discovered filovirus, is considered a potential human pathogen. The VP30 C-terminal domain (CTD) of these filoviruses plays an essential role in virion assembly. In common with other filoviruses, MLAV VP30 CTD mainly exists as a dimer in solution. In this work, we determined the crystal structure of recombinant MLAV VP30 CTD monomer, verifying that C-terminal helix-7 (H7) is critical for the dimerization process. This study provides a preliminary model for investigation of MLAV VP30 CTD as an anti-filovirus drug development target. (C) 2020 Elsevier Inc. All rights reserved.
