| Abstract: | 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°C, 4°C and –20°C. However, none of these proteins stabilized the invertase at or above 55°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. |
