CC -!- FUNCTION: Provides the cells with the ability to utilize trehalose at
CC high osmolarity by splitting it into glucose molecules that can
CC subsequently be taken up by the phosphotransferase-mediated uptake
CC system. {ECO:0000255|HAMAP-Rule:MF_01060}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha,alpha-trehalose + H2O = alpha-D-glucose + beta-D-
CC glucose; Xref=Rhea:RHEA:32675, ChEBI:CHEBI:15377, ChEBI:CHEBI:15903,

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01060};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01060}.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_01060}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 37 family.
