Abstract
A recent elegant cryo-electron tomography study of the populations of different GroEL-GroES chaperonins complexes in whole bacterial cells (Wagner, Carvajal et al. 2024) contributes to the resolution of a long-standing debate about their mechanism, and reconciles three-decade-old results from in vitro biochemical studies, with new, refined in situ observations. Biochemists working with purified proteins often wonder if their findings faithfully reflect the situation in the crowded environment of cells, when their proteins mingle with concentrated metabolites and bump into membranes and thousands of different unrelated proteins. Here, cryo-electron tomography confirmed that careful in vitro protein biochemistry research still has a bright future.
期刊介绍:
Cell Stress and Chaperones is an integrative journal that bridges the gap between laboratory model systems and natural populations. The journal captures the eclectic spirit of the cellular stress response field in a single, concentrated source of current information. Major emphasis is placed on the effects of climate change on individual species in the natural environment and their capacity to adapt. This emphasis expands our focus on stress biology and medicine by linking climate change effects to research on cellular stress responses of animals, micro-organisms and plants.
