The properties of purified cell envelope polyphosphatase, polyphosphatase activities of vacuoles and cytosol fractions of the Saccharomyces cerevisiae yeast have been compared. The whole body of evidence presently available suggest that each of the compartments under study is equipped with its own polyphosphatase which differs from polyphosphatases of other organelles. It is proposed that the organelle specificity of yeast polyphosphatases may reflect the endosymbiotic origin of eucaryotic cells.
已对纯化的细胞膜多磷酸酶的特性、酿酒酵母液泡和胞质溶胶部分的多磷酸酶活性进行了比较。目前现有的全部证据表明，所研究的每个区室都配备有自身的多磷酸酶，该酶与其他细胞器的多磷酸酶不同。有人提出，酵母多磷酸酶的细胞器特异性可能反映了真核细胞的内共生起源。
