Durch Hitze ausgelöster Stress führt zur Fehlfaltung und Aggregation von zellulären Proteinen. Inwiefern das Proteinqualitätskontrollsystem bestehend aus Proteasen und Chaperonen das Gleichgewicht zwischen gefalteten und beschädigten, fehlgefalteten oder sogar aggregierten Proteinen unter Hitzestressbedingungen wiederherstellt, ist von großem Interesse. In diesem Sinne wurde in dem Modellorganismus Bacillus subtilis die Thermotoleranzentwicklung im Hinblick auf die Entstehung von Proteinaggregaten in stark hitzegestressten Zellen, die zuvor einem milden Hitzeschock ausgesetzt worden waren, untersucht. Zellen, in denen das ClpXP-Proteasesystem fehlte, wiesen deutlich weniger hitze-induzierte Proteinaggregate auf, während Chaperone wie DnaK o...
