研究人员检查了蓝藻（蓝绿藻）聚球藻对 47 摄氏度热激的反应。菌株PCC 6301。在热休克时，细胞生长减少，并且优先合成有限数量的多肽。这些蛋白质的合成速率在升温初期显着增加，随后逐渐下降。根据钠离子迁移率，受温度升高影响较大的蛋白质包括表观分子量为 91,000 (91K)、79K、78K、74K、65K、64K、61K、49K、45K、24K、22K、18K、16K、14K、12K 和 11.4K 的蛋白质十二烷基硫酸盐-聚丙烯酰胺凝胶。根据这些对聚球藻的初步研究。对于 PCC 6301 菌株，我们得出结论，在蓝细菌中可能存在类似于已知在其他真核生物和原核生物中发生的热休克反应。
The response to heat shock at 47 degrees C was examined in the cyanobacterium (blue-green alga) Synechococcus sp. strain PCC 6301. On heat shock, the growth of the cells decreased and they preferentially synthesized a limited number of polypeptides. The rate of synthesis of these proteins increased markedly in the early period of temperature shift up and gradually decreased afterwards. Among the proteins greatly affected by temperature shift up were those with apparent molecular weights of 91,000 (91K), 79K, 78K, 74K, 65K, 64K, 61K, 49K, 45K, 24K, 22K, 18K, 16K, 14K, 12K, and 11.4K, based on their mobilities in sodium dodecyl sulfate-polyacrylamide gels. From these initial studies on Synechococcus sp. strain PCC 6301 we conclude that in cyanobacteria a heat shock response similar to that known to occur in other eucaryotes and procaryotes might exist.
