Occurrence of "stress"-proteins in yeast after heat-shock, acrylonitrile treatment and during the stationary growth phase.
The response of yeast cells to different kinds of "stress" is not identical. Cells of the stationary growth phase synthesize three new proteins of molecular weights 68, 27 and 24 kD, compared with cells of the exponential growth phase, while heat-shocked cells exhibit new proteins of 100, 90, 84, 70 and 24 kD. After treatment with acrylonitrile two new proteins with molecular weights of 70 and 46 kD appear. However, all three kinds of "stress" lead to the induction of a ribonuclease.
