Heat Shock Proteins of Cyanobacterium Anacystis nidulans

Cells of Anacystis nidulans grown at 30°C were incubatedwith ¹⁴C-Chlorella protein hydrolysate at the elevated temperatures(30–55°C) and the effect of heat shock treatment onprotein synthesis was studied. Incubation temperatures higherthan 45°C caused a significant decrease in the incorporationof amino acids into proteins. Further, the heat shock treatmentinduced significant changes in the fluorographic profile ofthe newly synthesized proteins. (Received October 25, 1985; Accepted December 4, 1985)
