Abstract
Collective transcriptional analysis of heat shock response in the hyperthermophilic archaeon Pyrococcus furiosus was examined by using a targeted cDNA microarray in conjunction with Northern analyses. Differential gene expression suggests that P. furiosus relies on a cooperative strategy of rescue (thermosome [Hsp60], small heat shock protein [Hsp20], and two VAT-related chaperones), proteolysis (proteasome), and stabilization (compatible solute formation) to cope with polypeptide processing during thermal stress.
摘要
利用靶向cDNA微阵列结合Northern分析，对嗜热古菌激烈火球菌热休克反应进行了集体转录分析。差异基因表达表明，激烈火球菌依靠救援协同策略（热体[Hsp60]、小热休克蛋白[Hsp20]和两种与VAT相关的伴侣蛋白）、蛋白水解（蛋白酶体）和稳定化（相容性溶质形成）来应对热应激期间的多肽加工。
