Dear Friends, I have a question about judging a homology model. I have three homologous proteins A, B and C of which only A has 3D crystal structure available. Their similarities/identities are given below. Pair-wise alignment similarity/identity (%) A and B

Hi Raja, 1) how big is your protein ? 2) multiple domains ? What's the ID/sim between domains ? 3) Check Xtalpred in case you've overlooked a closer homolog http://ffas.burnham.org/XtalPred-cgi/xtal.pl I would not try to predict an intermediate model and then use that to predict the final mode
