Hi Rui Very easy to use is EsyPred3D :
http://www.fundp.ac.be/sciences/biologie/urbm/bioinfo/esypred/ Also good performance server is 3d-JIGSAW : http://bmm.cancerresearchuk.org/~3djigsaw/ Hope it helps Cheers Francisco > Hi, All > Suppose I have two proteins A and B, they are structurally homologous, > however the sequence identity is only about 20%.
