Residue-residue correspondences between functional motifs in domain-fusion template 2ftk and SpaK (A) or SpaR (B) homology models.

1Residue.
2Residue name in PDB or model file.
3Distance between C-alpha carbons (under global superposition).
4RMSD(3): Root mean square deviation along the mainchain atoms
(N,CA,C,O) averaged over three residues: current and immediate
neighbors along peptide chain (local superposition).
5X – aspartic acid (ASP) modified to aspartate beryllium
trifluoride (BFD).
2ftk_A corresponds to Spo0B, and 2ftk_E corresponds to Spo0F. Letters
in bold represent corresponding functional residues. Neighboring
residues within 1 position of functional residues are included in
order to provide a sequence-structure context in which highlighted
residues were located. A) Residue-residue correspondences between
histidine phosphorylation site and neighboring residues of 2ftk
chain A and those of SpaK. B) Residue-residue correspondences
between regions containing 6 functional residues of 2ftk chain E and
SpaR.
