REFINEMENT PROTOCOL--RIGID BODY DETAILS--The domains were separately fitted with the global fitting option of the routine fitmap within UCSF-Chimera. Best fit was chosen based on the maximum cross-correlation value between the EM density and an 11 A resolution density model of the atomic structure of the domain to be fitted.
