[Molvis-list] Major errors in NMR structures from premier groups

[Eric Martz]

An amazing and somewhat alarming report in the February issue of PLoS Comp 
Biol is entitled

"Traditional Biomolecular Structure Determination by NMR Spectroscopy 
Allows for Major Errors"

Nabuurs, Spronk, Vuister and Vriend identify several published NMR 
structures containing major errors, and conclude that current methods for 
quality assessment of NMR-based models permit such errors at a worrisome rate.

They state "It is interesting to note here that the three erroneous 
structures described in this paper stem from premier protein NMR groups, 
all involved in the development of structure validation and refinement 
methodologies [refs], and that these methodologies either failed or were 
not or incorrectly applied in identifying the serious errors present in 
these structure ensembles."

Also interesting, they found no evidence for a difference in the likely 
error rate between structural genomics groups vs. individual research groups.
