The mutations in the B.1.1.529 variant are in its spike protein, “the part of the virus that most vaccines use to prime the immune system against Covid”, said the newspaper. variant mutations Variant Delta spike P681R mutation enhances SARS-CoV-2 fitness over Alpha variant. Effects of common mutations in the SARS-CoV-2 Spike RBD and its ligand, the human ACE2 receptor on binding affinity and kinetics. The image displays the structure of the Omicron spike protein beside that of the Delta variant, revealing a far higher rate of mutation. All the nine mutations of the Beta variant are located at the S1 region and C-terminal S2 of the spike protein. The three-dimensional “image” shows that the number of mutations in Omicron is double the mutations in Delta variant of coronavirus. During the current SARS-CoV-2 pandemic, a variety of mutations have been accumulated in the viral genome, and currently, four variants of concerns (VOCs) are considered as the hazardous SARS-CoV-2 variants to the human society[1][1].

A new variant of Covid-19, feared to have a high amount of spike mutations unseen before, has been detected in South Africa, with authorities there confirming 22 positive cases associated with it on Thursday. The image displays the structure of the Omicron spike protein beside that of the Delta variant, revealing a far higher rate of mutation. The Delta variant was resistant to neutralization by some anti-NTD and anti-RBD monoclonal antibodies, including bamlanivimab, and these antibodies showed impaired binding to the spike protein.

The mutation of SARS-CoV-2 to delta variant is observed through the spike proteins of the virus. And as with earlier variants, Omicron researchers are focused on numerous changes to the spike protein, which studs the surface of SARS-CoV-2 and allows it to latch on to and invade human cells. All the nine mutations of the Beta variant are located at the S1 region and C-terminal S2 of the spike protein. Elife 10:e70658.

Changes to the spike make it difficult for current jabs to fight off, because they train the immune system to recognise an older version of this part of the virus. The image shows the structure of the Omicron spike protein - the part of the virus that allows the viruses to penetrate host cells and cause infection (and which a vaccine targets) - alongside the spike protein of the Delta variant, illustrating a much higher rate of mutation with 43, compared to only 18 for the Delta variant. The variant — which the World Health Organization has named Omicron — has 32 mutations on the spike protein — the most ever recorded and twice as many as the currently dominant Delta strain.
