Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:In this analysis, positive folding free energy contributions indicate stability weaknesses sites and highly negative folding free energy contributions characterized sites of local stability in the S protein. For the locked closed form of the D614 S trimer, the stability hotspots are distributed across multiple regions including the NTD residues, the RBD core and the S2 domain regions (Figure 7A). It is worth noting that the most prominent stability centers were found in the RBD core and the region near the hinge hotspot cluster (residues 591-600) that featured stability peaks for hinge sites S591, F592 and G593 (Figure 7A). In both closed and open forms of the D614 S trimer, the receptor binding motif (RBM) of the RBD region (residues 470-491) showed only marginal stability as the energetic plasticity of this region is required for functional interactions with ACE2. In the open form of the D614 S trimer, the stability of the RBD core and S2 regions was partially reduced while maintaining the overall stabilizing signature in these positions (Figure 7B). By highlighting positions of circulating mutations K417, E484, N501 and D614 we noticed that D614 corresponds to a moderately stable position while other sites are marginally destabilizing (Figure 7A,B). Hence, mutations in these sites can be easily tolerated without impairing protein stability of the S trimer (Figure S1A) The overall stability pattern in the G614 S trimer remained preserved, highlighting similar regions of hig...
