Three maltases have been detected in each of a variety of strains of Saccharomyces. These are present in constant relative amounts in a particular strain and are characterized by reproducible first order thermal decay constants. Four of six mutants, temperature-sensitive for maltose fermentation, lack the maltase of intermediate stability. This deficiency appears to be the basis of the temperature sensitivity, and it is concluded that these strains carry a mutation in the structural gene for that maltase.
在多种酿酒酵母菌株中，每种都检测到了三种麦芽糖酶。这些麦芽糖酶在特定菌株中以恒定的相对含量存在，并具有可重复的一级热衰变常数。六个对麦芽糖发酵温度敏感的突变体中有四个缺乏稳定性中等的麦芽糖酶。这种缺陷似乎是温度敏感性的基础，由此得出结论，这些菌株在该麦芽糖酶的结构基因中发生了突变。
