Result: As a result, the
H625R-mutant
spike protein may exhibit differential biochemical properties, which should be further investigated, since they may have a severe impact on the functionality of the protein, making the virus more transmissible and/or infectious.
Result: Even though two similar amino acids are substituted, based on the in silico protein structure analysis,
H625R leads to subtle alterations in the
spike protein folding (Figure 5).
Result: In addition to the characterized
D614G mutation, a previously unknown point mutation within
S gene,
H625R (
23436A>G), was found at a frequency of 5.7% in September samples.
