In order to have MC-HELAN analyze one pdb file please fill out the form below and click 'Submit'

Please consult the documentation for instructions on filling out this form and interpreting the output.

(Required) Please enter a 4 character PDBid* or choose a PDB file to upload:
* MC-HELAN will automatically search the PDB_TM for a .trpdb file and .xml file. If no files are found a .pdb file is used from the PDB.

You have the option to receive your data by e-mail instead of waiting (Enter up to three space delimited addresses)



If this is a membrane protein, and you have provided your own .trpdb file, you may upload a PDB_TM XML file to define the TM helicies.
For accurate angles relative to the membrane, PDB file entered above must be a transformed PDB file (.trpdb) from the PDB_TM or TMDET)


Only analyze the following models (enter space delimited numbers,MC-HELAN defaults to analyzing all models)



Only analyze the following chains (enter space delimited letters (case sensitive), MC-HELAN defaults to analyzing all chains)



Use these initial helicies as a starting point: (not recommended)
Define helicies by their first and last residue numbers in the following format: 167-187 189-199 200-210





Topology Diagram Options (only produced for membrane proteins with a .xml file and .trpdb file):

Annotate the kink angles kink residues Nothing

Show the N-terminus at the:
bottom of the diagram
top of the diagram
attempt to use TOPDB to determine topology

Annotate the first and last residue of each helix

Draw all helices (vs. only transmembrane helices)

Draw all disruptions (vs. only transmembrane disruptions)

Save my final file as .zip .tar.gz

If you have any trouble using this MC-HELAN interface, please look at the documentation and then contact MC-HELAN for support.
