Key result
RBD mutations, particularly L452R, reduce the binding affinity of many antibodies through changes in geometric complementarity and entropy-enthalpy compensation, potentially causing breakthrough infections.
Why the study?
Understanding the physical mechanism behind mutation-induced changes in SARS-CoV-2 RBD binding affinity, transmissibility, and vaccine escape was an urgent challenge for developing COVID-19 countermeasures.
Thermodynamic analysis of SARS-CoV-2 RBD mutations reveals that specific mutations like L452R alter binding affinity and geometric complementarity, providing a physical mechanism for vaccine escape and breakthrough infections.

May explain variant breakthrough infections; animal data leave open human relevance and vaccine update needs.
Yang et al. (2021) studied COVID-19. RBD mutations (e.g., L452R) was evaluated on Binding affinity of SARS-CoV-2 variants with ACE2 and antibodies. RBD mutations, particularly L452R, reduce the binding affinity of many antibodies through changes in geometric complementarity and entropy-enthalpy compensation, potentially causing breakthrough infections.
