Abstract: S1.00124 : Exploring the effects of Hofmeister series ions on structural dynamics of water
Author:
Water is known as the lubricant of life. Most proteins lose their
biological
function upon dehydration. We found that in a variety of high
concentration
salt solutions, photoactive yellow protein, a blue light bacterial
photoreceptor protein, loses its functionally important
structural motions
for receptor activation. We hypothesize that this effect is
caused by
reduced structural dynamics of water due to strong water-ion
interactions.
Here we report our experimental studies on the effects of salts
on changes
in structural dynamics of water at different time scales. The
results are
expected to provide deep insight regarding how Hofmeister series
ions alter
the structural dynamics of proteins.
