FIGURE 5.

Fragments of spike protein generated due to cleavage at cathepsin putative sites in the N‐terminal domain. From PyMol, fragments created from cleavage by multiple cathepsins at two sites on spike protein are shown for (a) S50 through V213, a 19 kDa fragment, (b) S50 through E224, a 21 kDa fragment, (c) S510 – I119, an 8 kDa fragment, and (d) V120 through E224, a 12 kDa fragment. Protomers are shown on the left and spike protein trimers are shown on the right for each cleavage site pair
