title: [Synthesis of heat-shock proteins in Saccharomyces cerevisiae protoplasts].
abstract: The effect of cellular capsule elimination in Saccharomyces cerevisiae yeasts (protoplast formation) on the heat-shock protein synthesis and the synthesis of the proteins in protoplasts were studied. The methods of mono- and dimeric electrophoresis have demonstrated that (1) about 18 heat-shock proteins with the molecular masses 26-98 Kd are synthesized in cells at 41 degrees C; (2) protoplast formation per se does not induce the synthesis of heat-shock proteins, but the induction of these proteins in protoplasts at 41 degrees C is similar to the one in intact cells. The protoplast formation induces the synthesis of specific proteins different from heat-shock proteins and the synthesis is inhibited by the heat-shock. The heat-shock induces modification of 88 and 86 Kd heat-shock proteins. It inhibits the synthesis of a number of peptides (15-50 Kd) in cells and protoplasts.
