Protein name

RecName: Full=Periplasmic trehalase; EC=3.2.1.28; AltName: Full=Alpha,alpha-trehalase; AltName: Full=Alpha,alpha-trehalose glucohydrolase; Flags: Precursor;

Gene name

treA

FUNCTION: Provides the cells with the ability to utilize trehalose at high osmolarity by splitting it into glucose molecules that can subsequently be taken up by the phosphotransferase-mediated uptake system (By similarity).

CATALYTIC ACTIVITY: Alpha,alpha-trehalose + H(2)O = 2 D-glucose.

SUBUNIT: Monomer (By similarity).

SUBCELLULAR LOCATION: Periplasm (By similarity).

SIMILARITY: Belongs to the glycosyl hydrolase 37 family.
