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   -!- 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.
CC       {ECO:0000255|HAMAP-Rule:MF_01060}.
