Overview

Over 2500 experimental structures have been determined in a little over 7 years of protein structure initiative (PSI). About 82% of those structures originated from one of the 4 large-scale centers (BIG4) and over 55% of those were determined over the last 3 years. The BIG4 consortia continue to produce largely novel structures with very high modeling leverage.

Numbers of experimental structures from PSI

Target status from TargetDB (since September 1, 2000)

Status	Number of targets
Cloned	99093
Expressed	58163
Soluble	22797
Purified	23337
Crystallized	9492
Crystal Structure	2969
NMR Structure	287

Targets in PDB*	3558

*note that the number of targets with experimental structures is typically smaller than the number of PDB depositions from PSI (see above), as there can be multiple redundant structures for the same target.
