摘要
A highly purified invertase from a thermophilic fungus Thermomyces lanuginosus showed enhanced activity when incubated with exogenous proteins. These proteins also stabilized the invertase when incubated at 50 degrees C, 4 degrees C and -20 degrees C. However, none of these proteins stabilized the invertase at or above 55 degrees C, the temperature of inactivation. This property was found to be specific for the thermophilic invertase, as no such activation was observed for the mesophilic invertases from yeasts.
