This program searches the Protein Data Bank for entries that have a unit cell similar to your structure. Cell parameters are obtained from the CRYST record in your input file; molecular weight is deteremined from the atom records, and matthew's coefficent is calculated.

This server only compares cell parameters. To search the PDB using more parameters, pdbU can include Vm, MW, and cell volume in the search along with cell parameters.
