Anaerococcus senegalensis strain JC48T sp. nov. is the type strain of A. senegalensis sp. nov. a new species within the genus Anaerococcus. This strain whose genome is described here was isolated from the fecal flora of a healthy patient. A. senegalensis is an obligate anaerobic coccus. Here we describe the features of this organism together with the complete genome sequence and annotation. The 1,790,835 bp long genome (1 chromosome but no plasmid) contains 1,721 protein-coding and 53 RNA genes including 5 rRNA genes

Middle East respiratory syndrome coronavirus (MERS-CoV) is a human pathogen responsible for a severe respiratory illness that emerged in 2012. Structural information about the proteins that constitute the viral particle is scarce. In order to contribute to a better understanding of the nucleoprotein (N) in charge of RNA genome encapsidation, the structure of the C-terminal domain of N from MERS-CoV obtained using single-crystal X-ray diffraction is reported here at 1.97 Å resolution. The molecule is present as a dimer in the crystal structure and this oligomerization state is confirmed in solution, as measured by additional methods including small-angle X-ray scattering measurements. Comparisons with the structures of the C-terminal domains of N from other coronaviruses reveals a high degree of structural conservation despite low sequence conservation, and differences in electrostatic potential at the surface of the protein.
