This is a composite map produced with Phenix "combine focused maps" (1.20.1) with EMD-51413 (overall consensus map), EMD-51417 and EMD-51418 (focused maps of single strands), EMD-51438 and EMD-51439 (focused maps of central units from single strands)

 FLEXIBLE FIT
initially the crystal strucutre model of the heterodimer (PDB 6WMZ) was used for rigid fitting for the focused maps and further refined. The complete dimers of the focused models (PDB 9GLC and 9GLD) were used as templates for 4 repeats of the filament in the composite map (also containing the RRM1 domains by rigid fitting) to represent the biological assembly.
