Аннотация:The comparative study of the behavior of DsRed1, EYFP and ECFP under high pressure was carried out. We found that only chromophores of EYFP and ECFP were sensitive to pressure treatment. The result is interesting from the point of view of high structural similarity of DsRed1 and other studied proteins leading to the discovery of new properties in high pressure studies that wouldn't show up otherwise.
