 4A0P RIGID BODY FIT Coot
Protocol: Rigid Body. A homology model of LRP6 residues 20 to 1244 based on the LRP6P3E3P4E4 crystal structure was built using Modeller. This single rigid-body was manually docked into the electron microscopy reconstruction and subjected to automated real-space refinement in Coot. Residues linking E2 and P3 residues 628 to 632 were removed. The model was subsequently refined as two rigid bodies residues 20 to 627 and residues 633 to 1244 using Coot. Refined models were scored against the electron microscopy map using a real space correlation coefficient computing using the Bsoft package .
