Human coronavirus 229E ( HCoV-229E) is a species of coronavirus which infects humans and bats. [1] It is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the APN receptor. [2] Along with Human coronavirus OC43 (a member of the Betacoronavirus genus), it is one of the viruses responsible for the ...
The nucleocapsid (N) protein is a protein that packages the positive-sense RNA genome of coronaviruses to form ribonucleoprotein structures enclosed within the viral capsid. [2] [3] The N protein is the most highly expressed of the four major coronavirus structural proteins. [2] In addition to its interactions with RNA, N forms protein-protein ...
SARS-related coronavirus is a member of the genus Betacoronavirus (group 2) and monotypic of the subgenus Sarbecovirus (subgroup B). [12] Sarbecoviruses, unlike embecoviruses or alphacoronaviruses, have only one papain-like proteinase (PLpro) instead of two in the open reading frame ORF1ab. [13] SARSr-CoV was determined to be an early split-off ...
COVID-19 recession. On 20 February 2020, stock markets across the world suddenly crashed after growing instability due to the COVID-19 pandemic. It ended on 7 April 2020.

The spike protein is very large, often 1200 to 1400 amino acid residues long; [8] it is 1273 residues in SARS-CoV-2. [5] It is a single-pass transmembrane protein with a short C-terminal tail on the interior of the virus, a transmembrane helix, and a large N-terminal ectodomain exposed on the virus exterior. [5] [7]
