Catalophore Studio
The Protein Cavity Workbench

See the binding site. Understand it. Design against it.

Catalophore Studio turns a raw protein structure into an interpreted binding site in seconds. It unites point-cloud cavity detection, 30+ physicochemical property fields, structure-aware AI reasoning, ligand preparation, docking and proteome-wide cavity search, all in one interactive workbench, powered by Innophore’s Catalophore™ technology.

01 · The Workflow

One continuous path from a PDB to a design decision.

Catalophore Studio covers the whole path in one workbench. Each stage hands the next exactly what it needs: load a structure, prepare it, find and read the pocket, then prepare, dock and refine a ligand against it.

Load & prepare

Structure

Open any PDB, fetch by ID from RCSB or UniProt, add hydrogens and parameterize ligands.

Detect

Cavities

Point-cloud detection annotates every pocket with 30+ property fields and geometry.

Interpret

AI reasoning

A structured biological read of the site: zones, mechanism, druggability, ligand strategy.

Design

Dock & refine

Prepare ligands, dock, score interactions and get AI-guided modification suggestions.

02 · Detect & Characterize

Every pocket, described as a field of measurable properties.

Catalophore Studio applies the validated Caviar algorithm to detect binding sites on a 3D grid, then annotates each grid point with the physicochemical environment a ligand would actually feel. The result is a property point cloud you can read, color, slice and quantify.

Geometry

Shape you can trust

Volume, dimensions, sphericity, depth and lining residues for every detected cavity, plus tunnel and constriction detection for buried or channel-like sites.

Property fields

30+ annotations per point

Hydrophobicity, polarity, nucleophilicity, Coulomb potential and electric field, element-specific van der Waals probes, metal / π–π / cation–π hotspots, flexibility and LigSite score.

Visualize

Read it instantly

Color any property on the point cloud, inspect its distribution as a histogram, generate contour maps and titration profiles, and explore the structure in cartoon, stick or surface styles.

03 · Interpret

An expert read of the binding site, grounded in the numbers.

Catalophore Studio interprets the binding site, not just renders it. A deterministic analysis pipeline distills thousands of grid points into rigorous statistics, then a reasoning model returns a structured, evidence-cited biological assessment.

  • Ab initio. The model sees only cavity geometry and properties, never the protein’s name, so the read is unbiased by prior annotation.
  • Nine structured sections. Executive summary, geometry, composition, electrostatics, hydrophobicity pattern, functional zones, mechanism, EC classification and ligand recommendations.
  • Choose the lens. Tell it whether your focus is catalysis or drug discovery and the interpretation adapts.
  • Honest about itself. Every section reports a confidence level and explicit limitations, with no black-box certainty.

Structured AI interpretation. An executive summary with key features highlighted, plus a one-click choice of analysis lens.

1

Geometry & property statistics

Volume, sphericity and full descriptive statistics for all 30+ properties.

2

Spatial gradients & functional zones

Directional and radial trends; extrema clustered into catalytic centers, specificity pockets and exit channels.

3

Composition & residue influence

Lining residues classified by chemistry; each residue’s quantified effect on the local environment.

4

Reasoning & mechanism illustration

The curated report drives the structured interpretation and, for enzyme sites, a publication-style mechanism diagram.

A 10-module deterministic pipeline runs before any AI call, so interpretations are anchored in quantitative analysis rather than raw-data speculation.

Precisionat the atom.

A binding hypothesis is only as good as the chemistry of the molecule you test. AI structure and ligand pipelines move fast, but they still get stereochemistry wrong often enough to matter: by one benchmark, chirality errors occur in 4.4% of cases.

That is why Catalophore Studio builds ligand preparation on explicit, validated chemistry: RDKit-backed stereochemistry and tautomer analysis, stereoisomer and tautomer enumeration, plus GAFF2 atom typing and charge assignment via AnteCaviar. What you dock is chemically correct, not merely plausible.

04 · Prepare & Dock

From a clean ligand to a scored, interpreted pose.

Once you understand the pocket, design against it. Catalophore Studio prepares ligands rigorously, docks them into the detected cavity, and analyses the result both geometrically and mechanistically.

  • LigPrep. Enumerate conformers, stereoisomers and tautomers; analyze stereochemistry and bond orders before docking.
  • AnteCaviar. GAFF2 atom typing and partial charges, exportable for downstream tools.
  • Docking, single or batch. Pose generation, binding scores, full docking history and per-interaction breakdowns.
  • SAR built in. R-group decomposition, matched molecular pairs, activity cliffs and scaffold analysis across a series.
05 · AI-Guided Design

The model tells you what to change, and why.

Every pose can be sent to an AI analysis that reads the interactions against the cavity’s own property fields, then proposes concrete, chemically reasoned modifications and a mechanistic view of likely PK behaviour.

  • Modification suggestions tied to real features: fill volume near a constriction, rigidify a flexible chain to cut entropy loss, or add a basic donor to engage a specific aspartate.
  • Mechanistic PK analysis that turns a binding result into a hypothesis about exposure and behaviour.
  • Interaction mapping linking each suggestion back to hydrophobic, electrostatic or steric potential at the binding site.

Every analysis becomes context the AI can reason over.

Catalophore Studio keeps a living knowledge base of your project. Cavity analyses, docking results and proteome matches are captured automatically; drop in a PDF paper and it is parsed for structures, database IDs and findings. Drag any entry into the chat and the copilot reasons with it.

Auto-captured
