Three powerful tools for molecular research

From small molecule docking to de novo protein design—integrated workflows for computational biology.

hub
Docking

AutoDock Vina

Virtual screening for drug discovery. Predict how small molecules bind to protein targets and rank compounds by binding affinity.

  • check Interactive docking box definition
  • check Batch virtual screening
  • check 3D pose visualization
  • check CSV/PDBQT export
hub
Protein Design

ProteinMPNN

Design protein sequences for given backbone structures. Generate sequences that fold into your target conformation.

  • check Fixed position constraints
  • check Chain-level design control
  • check Multiple sequence generation
  • check FASTA export
hub
Ligand-Aware

LigandMPNN

Design proteins that bind specific ligands. Engineer enzymes and binding proteins considering ligand interactions.

  • check Ligand context awareness
  • check Configurable cutoff distance
  • check Side-chain packing
  • check FASTA export

One platform for your molecular design workflow

Stop switching between tools. MolNexus integrates docking and protein design in a unified interface.
