Figure 1. SARS CoV-2 genome organization and mutations in structural proteins. Frequency of mutations has been shown.
Figure 2. Stability prediction of N501Y. The mutant (Y501) seems more stable than wild type residues (N501). The Y501 has been detected in 4362 genome sequences, prevalent in 48 countries. The prediction was performed through DynaMut server[16].
Figure 3. Frequency of mutations in SARS-CoV-2 spike proteins. (A) SP: signal peptide, NTD: N-terminal domain, RBD: receptor-binding domain, RBM: receptor binding motif, FP: fusion peptide, HR: heptapeptide repeat sequence, TM: transmembrane region, CT: cytoplasmic tail. S1 (14–685aa) includes, NTD (14–305aa), RBD (319–541aa), RBM (aa437–508). S2 (686–1273aa) include FP (788–806aa), HR1 (912–984aa), HR2 (1163–1213aa), TM (1214–1237aa) and CP (1238–1273aa) S2 subunit. (B) Domains with mutations. RBD: ACE binding residues and mutations.

NTD: N-terminal domain (43-174aa), SR-Linker: serine and arginine rich region (194-225aa), CTD: C-terminal domain (257-364aa), RBD: RNA binding domain (40-180aa), PS: phosphorylation sites (186, 197, 202, 204 aa). (B). Crystal structure of NTD and most common variants.
