Welcome to the M-ZDOCK homepage. M-ZDOCK is a program for predicting the structure of a radially symmetric multimer based on the structure of a subunit. It uses a fast Fourier transform (FFT) to search efficiently for the best position of adjacent subunits, then generates the multimer once the best position is found.


Software
Downloads of the M-ZDOCK program are available for Linux, IBM p690, and Mac OS X platforms.

Multimer Applet
M-ZDOCK is based on the concept that a Cn multimer can be generated by putting two adjacent subunits anywhere in the plane that is perpendicular to the axis of rotation (the subunits just need to be rotated 360/n degrees from each other in this plane). We wrote an applet to show this concept, where you can vary the degree of symmetry, the shape of the subunits, and show/hide the rest of the multimer. If you have trouble loading the applet, you may need JRE 1.4.2.

Supplemental Information
Table listing the residues for each multimer testcase that moved significantly upon binding, consequently ignored for evaluation of the rigid-body predictions.
