The peptide identity is retained at sequence or backbone level, but the current evidence does not identify a specific chemical form. This is not evidence that the peptide is unmodified.

Soft tints mark standard side-chain classes for scanning. Primary emphasis is reserved for reported modifications, termini, secondary-structure tracks, and topology links.

Peptidoform features

Features are shown only when a reported notation or topology record supports them.

No terminal modification, residue-level marker, disulfide, staple, coordination, or other topology signal is currently available.

Not available
No atom-level graph

A reviewed SMILES is required before a 2D molecular depiction can be shown. Sequence and HELM remain useful for identity interpretation, but they do not replace a chemical graph.

3D structure referencesnone attached
3D structure not available

A 3D structure isn't available for this peptide in the current release. Chemistry and topology fields remain available when represented by sequence, HELM, or SMILES.

Covalent topology & modificationsnone
Exact topology not established

No reviewed form-level topology or residue-level connection annotation is attached to this peptide in the current release. This is not evidence that every molecular form is linear or unmodified.

The pale sector marks the direction of the hydrophobic face inferred from μH. This is a projection assumption, not a measured fold.
HydrophobicAromaticPolarBasic +Acidic −Specialhydrophobic faceμH arrow → hydrophobic face

The projection assumes an α-helix conformation; a long μH arrow indicates an amphipathic helix, common in antimicrobial peptides.Sequence > 30 aa — only termini and every fifth position are numbered because later turns share earlier wheel angles.

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
108.84
Instability index

Above 40 — predicted unstable in vitro.

Boman index

Above 2.48 — elevated potential protein-binding.

Molar extinction coefficient (280 nm)

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.
