Fitting Procedure ?
Details First, rigid body fit was performed in Chimera using the coordinates of the TMD of 6QKC and the coordinates of the LBD in PDB code 3TKD. Manual model building was performed with Coot and Refinement was performed with Refmac. The TMD and LBD maps obtained independently aided model building but were not used for refinement.
