Structural highlights

6svb is a homotrimer transmembrane glycoprotein(S) protruding from the viral surface¹. There are two subunits which are fundamental for the virus entry in the cell: the S1 subunit, responsible for binding to the host cell receptor, and the S2 subunit, responsible for fusion of the viral and cellular membranes.

Function

The spike glycoprotein reconizes the hosts cell's angiotensin-converting enzime 2 (ACE2) receptor and binds itself on it, allowing the fusion of viral and cellular membrane.

Disease

6vsb is a protein related to the virus entry in the cell. Therefore, has an enormous role on the new coronavirus pandemic, in 2020.

Relevance

Potential target for antibodies. Development of vaccines based on the structure of the protein and on it's recognition/biding mechanisms.

Interaction with angiotensin-converting enzime 2 receptor

The interaction between the 2019-nCov and the host cell begins with the recognition of the ACE2 receptor. Then, the S1 subunit moves, modifying the protein's conformation in way that determinants for the virus-cell binding. Due to the conformational movements, the protein structure assumes a conformation which is suitable for binding with the ACE2 receptor. At that instance, the spike protein is found in a "up" conformation, hence the protein's name.
