đŸ”ĸ Residue Renumbering Tool

Renumber protein residues to match your original numbering scheme

Renumber Residues

The residue number to assign to the first amino acid in the structure

ℹī¸ How it works

This tool renumbers all standard amino acid residues in your PDB file sequentially starting from the number you specify.

Features:

  • Renumbers only standard amino acids (A-Z)
  • Preserves ligands and non-standard residues with their original numbering
  • Maintains protein structure and connectivity
  • Works with multi-chain proteins

Use Case: If your modeled structure has residues numbered 1-200 but they should be 340-539, this tool will fix the numbering.
