45 residues of pure loop. no helix, no sheet, just a long floppy ribbon doing nothing in particular. composition is all over the place too, like the sequence never committed to a structural opinion.

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 isomerization motif (D-G), contains methionine; oxidation sensitivity possible, multiple cysteines; disulfide heterogeneity 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 44% (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 100% (high)
