A virus that has gone viral: Amino acid mutation in S protein of Indian isolate of Coronavirus COVID-19 might impact receptor binding and thus infectivity

The paper analyzes amino acid mutations in the S protein of Indian SARS-CoV-2 isolates, identifying a mutation at position 407 that may affect receptor binding and infectivity.

Two mutations P/L and Y/C in SARS-CoV-2 helicase domain exist together and influence helicase RNA binding

The paper identifies two mutations in SARS-CoV-2 helicase, P504L and Y541C, which have opposing effects on RNA binding affinity and are co-existing in some isolates.
