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.

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.
