Fitting Procedure ?
Details The coordinates of 7ngl subunits were fitted as rigid bodies into the low resolution density of the LonP1 D2-state. The N-domains (res. 123-410) were fitted separately from the combined A- and protease domains (res 411-1001). The connecting loops (res 405-415) were reconnected with good geometry. Clashes between the rigid bodies were not corrected due to the low resolution.
