Introduction: There are seven substitutions (
N501Y,
A570D,
D614G,
P681H,
T716I,
S982A, and
D1118H) and three deletions (H69Del, V70Del, and Y144Del) in the
spike of the
N501Y.V1 variant comparing with the Wuhan-Hu-1 strain (wide type), with
N501Y the only mutation in the ACE2 interface of the
receptor binding domain (
RBD).
