pep
“64 residues of pure loop. no helix, no sheet, just a long floppy string drifting through space. lots of charge scattered around too, which probably isn't helping it commit to anything.”

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: 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: 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 35% (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)
