Protection against thermal denaturation by trehalose on the plasma membrane H+-ATPase from yeast. Synergetic effect between trehalose and phospholipid environment.


Yeast cells have had to develop mechanisms in order to protect themselves from chemical and physical agents of the environment to which they are exposed. One of these physical agents is thermal variation. Some yeast cells are known to accumulate high concentrations of trehalose when submitted to heat shock. In this work, we have studied the effect of… (More)
