The attachment is my target(442AA),i did PSI-blast, found 6 templates for 66-412AA,but for 1-65AA and 412-442AA,there is no template,how should i do in this condition? i want to use Threading or ab initio to model1-65AA and use homology modelling to model 66AA-411AA,the question is how can i join these predicted structures together to form one structure? is there any better methods for this condition?
