44 residues and not a single hint of structure. pure loop, completely floppy, like a sentence with no punctuation. composition isn't even that bad, lots of hydrophobics that should want to fold something, but here we are.

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, long hydrophobic run may increase aggregation risk. minimal substitutions usually suffice (e.g. N→Q for deamidation hotspots, M→L for met oxidation).

    trigger: 3 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 53% (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 98% (high)
