Scientists predict driver mutations of future SARS-CoV-2 variants of concern

A team of scientists from the USA has recently predicted the driver mutations that may appear in future variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The prediction is based on currently available genetic surveillance data on amino acid mutations present in SARS-CoV-2 variants. A detailed description of the study is currently available on the medRxiv* preprint server.

Single mutation to bat virus spike protein allows cell entry using human ACE2

In a paper recently uploaded to the preprint server bioRxiv by Kirchhoff et al. (May 31st, 2021) it is demonstrated that a single mutation to the RaTG13 spike protein results in significantly greater affinity towards the human receptor, indicating that the presence of a positively charged amino group at this position better facilitates interaction with the human ACE2 receptor, and helping to identify other viruses with zoonotic potential.
