STELLAR

Advanced docking protocol for large flexible peptides — without AI.

About

STELLAR is a docking protocol developed at BIO-HPC for the docking of large peptides and other large, flexible ligands beyond the typical small-molecule range. It does not rely on AI methods, using instead a fragment-and-assemble strategy with HPC-distributed search.

Originally introduced in a cancer-context application, it is suited for problems where peptide ligands or large flexible biopolymers (e.g. glycans, polysaccharides) need accurate pose prediction.

Lead authors: Alejandro Rodríguez Martínez

Key features

Large-peptide docking

Beyond the small-molecule limits of conventional docking programs.

Fragment-based assembly

Splits flexible ligands into manageable fragments and reassembles consensus poses.

No AI dependency

Deterministic, physics- and geometry-based, useful where AI training data is scarce.
