Properties of phospholipase B from the yeast Torulaspora delbrueckii and its physiological effects on the durability of the yeast

Phospholipid deacylating enzymes of yeast have been studied primarily in Saccharomyces cerevisiae, a baker's yeast, and Candida albicans, a pathogenic yeast. In recent years, the genes of S. cerevisiae and Torulaspora delbrueckii have been cloned, providing derailed data on the physiological roles, structure, and activity of these enzymes in yeast. We report here on the results of our study on phospholipid deacylating enzymes, mainly the enzyme derived from T. delbrueckii, and discuss the physiological role of this enzyme in the cells of this yeast.
