pep
50 residues and not a single secondary structure element. completely loop, completely floppy, the kind of chain that just drapes wherever you put it. interesting that nothing wanted to fold, with this much sequence to work with.

what to do next

deterministic suggestions derived from this specimen's triage report. each entry cites the signal that triggered it. ordered cheapest-first.

  1. 1. LIABILITY REDESIGN ROUND
    in silico only · 0–1d

    redesign to remove the flagged motif(s) before going wet-lab: potential deamidation motif (N-G), contains methionine; oxidation sensitivity possible. minimal substitutions usually suffice (e.g. N→Q for deamidation hotspots, M→L for met oxidation).

    trigger: 2 motif liability flag(s) in the sequence
  2. 2. CD SPECTROSCOPY
    biophysical validation · 1–3d

    experimental secondary structure check. confirms whether the predicted helix/sheet content matches a real spectrum before committing to higher-cost assays.

    trigger: fold_confidence 55% (model is uncertain)
  3. 3. 1H-15N HSQC
    biophysical validation · 2–5d

    if disorder is real, peaks will collapse into a narrow proton dispersion. if the peptide is actually folded, peaks will spread out. cheapest way to distinguish IDP from misfold.

    trigger: disorder_estimate 76% (high)
