Run Heligeom

1st Oligomeric form

Upload a PDB file containing the two monomers or enter a PDB accession number.

If the button Retrieve Helical parameters is hit first, then the PDB file must be uploaded again.

For each monomer, you can specify either the chain of interest or/and the residue range which define the monomers or both.

Note: The tool can handle missing residues within the selection (to manage flexible/unstructured sections).

In this case, The 2 monomers must have a residue range filled with the same gap (i.e 1-300 and 301-600).

    You can specify a second couple of monomers to define another interface and compare it to the first one.

    Upload a PDB file containing the two monomeres or enter a PDB accession number.

    If the button Retrieve Helical parameters is hit first, then the PDB file must be uploaded again.

    Leave it blanck to use the structure defined in the first oligomeric form.

Construction Details

From the helical parameters calculated from the 2 monomers, you can construct a filament made of copies of Monomer 1.
