I submitted a contiguous AA sequence of about 400AA in single letter format. The model that was calculated, when displayed , shows two structures that are not connected . The first structure is about 160AA long and the second , which is not connected to the first and significantly displaced in space from it, is about 240AA long. The structures are not duplicates , they are distinctly different. Why would a contiguous sequence of AA submitted give a calculated model with two disconnected structures instead of one?
Any help would be really appreciated. Thanks in advance.
