Yfh1 residue numbers are those of 2FQL pdb, Cyay numbers are those of 1EW4 pdb, hfrat numbers are those of 1EKG pdb.
To do so we used the solid state structure of Yfh1 (PDB ID: 2FQL) which is at much higher resolution than the corresponding NMR structure (PDB ID: 2GA5).
Residue numbers are those of PDB ID:2FQL.
The outstanding chemical shift changes involving L102 and E103 are highlighted by arrows Residue numbers are those of PDB ID:2FQL.

Pdb 2ga5 and 2fql were excluded from the fragment search in order to have an unbiased calculation.
(A) Superposition of the Rosetta model (blue ribbon) with the x-ray structure of a mutant Yfh1 (green ribbon, pdb id 2fql).
The r.m.s.d. with the crystallographic structure (pdb id 2fql) is 2.05 Å (Figure 5A ), whereas the corresponding r.m.s.d. with the previous NMR structure (pdb id 2ga5) is 3.05 Å (Figure 5B ).
Residue numbers are those of pdb id:2FQL.

17 , 18 The conserved globular domain is thus preceded by an N-terminal tail that is specific to eukaryotes and is responsible for mitochondrial import (pdb code 2fql).
33 Interestingly, the residues that we detected in-cell are not visible in the crystal structure of a Yfh1 mutant (pdb id 2fql) designed to destabilize the first helix by mutating Y73 into an alanine.

Indeed, the analysis of several frataxin X-ray structures, from different sources (pdb id: 2fql [ 17 ], 1ekg [ 18 ], 1ew4 [ 19 ]), revealed no interaction between the N-state of the protein and sulfat... , chloride or sodium ions, even though these ions are very abundant in the crystallization conditions.
