A three-dimensional movie of structural changes in bacteriorhodopsin.
Bacteriorhodopsin (bR) is a light-driven proton pump and a model membrane transport protein. We used time-resolved serial femtosecond crystallography at an x-ray free electron laser to visualize conformational changes in bR from nanoseconds to milliseconds following photoactivation. An initially twisted retinal chromophore displaces a conserved tryptophan residue of transmembrane helix F on the...
متن کاملUnravelling the folding of bacteriorhodopsin.
The folding mechanism of integral membrane proteins has eluded detailed study, largely as a result of the inherent difficulties in folding these proteins in vitro. The seven-transmembrane helical protein bacteriorhodopsin has, however, allowed major advances to be made, not just on the folding of this particular protein, but also on the factors governing folding of transmembrane alpha-helical p...

For certain database tasks that require great exibility, some people are turning to a new kind of data representation in which the database is not constrained by a schema. Instead, each component of the database carries its own description, which is independent of other components. Systems like ACeDB, which has become very popular with biologists, and the recent Tsimmis proposal for data integr...

متن کاملGraduate school: the movie
T here is a series of documentaries trackmg a group of British schoolchildren every seven years, that began when they were all at age seven with a film called Seven-up, and has now passed age 35. The films were made with an explicit assumption that social class and innate character, properties already apparent in a seven-year old, would be the defining characteristics of the adult's life. While...
