Abstract
|
 |
|
The conformational changes during the photocycle of the photoactive yellow
protein have been the subject of many recent studies. Spectroscopic measurements
have shown that the photocycle also occurs in a crystalline environment, and
this has been the basis for subsequent Laue diffraction and cryocrystallographic
studies. These studies have shown that conformational changes during the
photocycle are limited to the chromophore and its immediate environment.
However, spectroscopic studies suggest the presence of large conformational
changes in the protein. Here, we address this apparent discrepancy in two ways.
First, we obtain a description of large concerted motions in the ground state of
the yellow protein from NMR data and theoretical calculations. Second, we
describe the high-resolution structure of the yellow protein crystallized in a
different space group. The structure of the yellow protein differs significantly
between the two crystal forms. We show that these differences can be used to
obtain a description of the flexibility of the protein that is consistent with
the motions observed in solution.
