Fig. 1. Changes to SCOP(e) design and size.

Fig. 1

All stable SCOP and SCOPe releases since the introduction of stable identifiers (SCOP 1.55, July 2001) are shown. The height of the vertical line for each release represents the number of PDB entries classified. The angle of the blue baseline between releases reflects the degree of divergence from comprehensive and fully manually curated releases. SCOP2 [31] is a major redesign of SCOP that enables curators to annotate a richer set of evolutionary relationships between proteins, providing a more precise and accurate characterization of protein relationships. SCOP2 is currently available as a prototype that classifies 995 proteins. A dashed line indicates that the SCOP2 prototype is partially based on SCOP 1.75.
