I want to build the structure of a protein that consists of multiple chains. One of my templates is homologous to the entire protein, but the other templates are only homologous to portions of the protein. I found an early post that suggests manually merging different structures into a sequence that’s homologous to the entire protein. Since this answer was posted in 2012, I wonder if is there any new approach to deal with structures that are homologous to different parts of the target?
