Reconstruction protein structures using the 23-state structural alphabet. Reconstruction of the (a) α-β-barrel protein (Protein Data Bank [PDB] code 1TIM-A ) and (b) ribonucleotide reductase (PDB code 1SYY-A ). The α-carbon root mean square deviation (rmsd) between the X-ray structures (red) and reconstructed proteins (green) are 0.80 Å (1TIM-A) and 0.63 Å (1SYY-A), respectively.
