THE SRP14 LOOP ELECTRON DENSITY CONNECTING 14B1-14B2 (34-47) IS WEAK SUGGESTING THAT THE LOOP IS FLEXIBLE. 5 C-TERMINAL AND 3 N-TERMINAL RESIDUES OF SRP9 AND 13 C-TERMINAL RESIDUES OF SRP14 HAVE POORLY DEFINED DENSITY. IN ADDITION, THE MODEL DOES NOT INCLUDE THE SRPF14-9 N-TERMINAL F EXTENSION (18 RESIDUES) NOR THE ENTIRE LINKER REGION OF WHICH ONLY 8 OF 17 RESIDUES ARE ORDERED.
