Antonio,
I think what you are looking for is homology modelling. You'd
need a pretty powerful computer to do this sort of work. However I
suggest the easy approach and connect to the swiss-prot database at:
http://expasy.hcuge.ch/
There you should find a swiss-model option which will do the modelling
for you. The results will be sent to you via e-mail. I suugest you read
their information pages first and take the structure you recieve with a
pinch of salt. Snail-mail me if you need any more help
Good luck
Simon
