X-raying ion channels
Trieste, Italy (SPX) Jun 28, 2015
"In this field, x-ray crystallography is considered the ultimate form of evidence: if something is demonstrated with this technique, then it just has to be true" explains SISSA professor Vincent Torre. Torre coordinated a study just published in the Proceedings of the National Academy of Sciences (PNAS) which used x-ray crystallography to demonstrate that the "selectivity filter" of ion channels is dynamic rather than rigid, thereby contributing to the solution to a long-standing debate among biop ... read more
