Hi Fei,
Just selecting is not enough.  You also have to turn on one of the mouse modes to move only the selected protein, by clicking on the icon for that mousemode (see link I gave before) or using the “mousemode” command.

Or, without doing any selecting, you can just use the “move” command with the “model” option to specify which model to move, as suggested by Tom.

When I opened the two complex one by one, the two proteins bind, and I can't move them by each other, even by selecting one of them. I'm not sure it's because the two protein complexes are too large or else. I'll appreciate it if you can help me solving the problem. Thanks.
