How to read this comparison

Download comparison JSON

Only annotation-core Cα atoms are shown. Thin guides connect consecutive canonical positions separated by at most 4.5 Å; they show the fold and are not all-atom covalent bonds. Sequence gaps remain visible.

The blue model uses the recorded Kabsch least-squares fit on US-align residue correspondence. The viewer does not use the separate TM-optimized US-align transformation.

Conservative display criterion (both TM scores ≥0.5 and both aligned fractions ≥0.8): 0. This criterion is a descriptive filter for short cores, not proof of equivalent pockets.

Fit statistics and normalization

US-align reported RMSD: 2.21 Å
Recomputed Kabsch RMSD: 2.21419 Å · transformation displayed above
RMSD under US-align TM transform: 2.316149 Å · separate, undisplayed transformation
Aligned fraction of Model A: 0.678571
Aligned fraction of Model B: 0.890625
Aligned sequence identity: 0.246

The two TM scores each use the corresponding observed crop length as their denominator. The JSON download includes both coordinate models, the applied transformation and all residue correspondences.
