In fungi, the hydrolysis of extracellular trehalose is carried out by acid trehalases. These secretory glycoproteins may be more abundant either in the vacuolar compartment, like in yeast, or at the cell surface, such as in many filamentous fungi. The relative efficiency of these two compartments fo...
