The projection assumes an α-helix conformation; a long μH arrow indicates an amphipathic helix, common in antimicrobial peptides.

Method notes

Charge model: side-chain pKa D 3.9, E 4.1, C 8.5, Y 10.1, H 6.5, K 10.8, R 12.5 with EMBOSS termini. pI is estimated by binary search on modeled net charge. Hydropathy uses Kyte-Doolittle values; hydrophobic moment follows the Eisenberg alpha-helix vector-sum convention. When the basis is a parent-residue sequence, modified chemistry is intentionally not inferred.

Computed developability descriptors

Deterministic descriptors computed from the reviewed sequence or chemical structure (RDKit), each anchored to a literature method. These are computed estimates for developability interpretation — not experimental measurements — and are validated against independent reference implementations.

Sequence-derived

Computed from the standard parent-residue sequence; protein-origin metrics defined at any length.

Aliphatic index
0.00
Instability index
71.5

Above 40 — predicted unstable in vitro.

Boman index
3.42 kcal/mol

Above 2.48 — elevated potential protein-binding.

Molar extinction coefficient (280 nm)
2,980 M⁻¹·cm⁻¹

A280 (1 g/L) ≈ 1.29

Structure-derived descriptors are not shown because this identity has no resolved chemical structure (SMILES). This is a known coverage gap for disulfide-rich and unresolved peptidoforms, not a computation error.

ADMETatlas
peptide evidence atlas

ADMETatlas is an open, curated atlas of ADMET evidence for therapeutic peptides — spanning developability, membrane permeability and blood–brain-barrier transport, immune-recognition context, and approved-product context. Every measurement stays linked to its original source, with stable identifiers and transparent curation, so results can be traced, cited, and reproduced.
