Abstract/Summary
|
-
A key question in structural biology is how protein properties mapped out under simplified conditions in vitro transfer to the complex environment in live cells. The answer, it appears, varies. Defying predictions from steric crowding effects, experimental data have shown that cells in some cases stabilize and in other cases destabilize the native protein structures. In this study, we reconcile these seemingly conflicting results by showing that the in-cell effect on protein thermodynamics is sequence specific: The outcome depends both on the individual target protein and on its detailed host-cell environment.
