CC   -!- FUNCTION: Hydrolyzes trehalose to glucose. Could be involved, in cells
CC       returning to low osmolarity conditions, in the utilization of the
CC       accumulated cytoplasmic trehalose, which was synthesized in response to
CC       high osmolarity. {ECO:0000255|HAMAP-Rule:MF_01059}.
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         ChEBI:CHEBI:16551, ChEBI:CHEBI:17925; EC=3.2.1.28;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01059};
CC   -!- PATHWAY: Glycan degradation; trehalose degradation; D-glucose from
CC       alpha,alpha-trehalose: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01059}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01059}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01059}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 37 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01059}.
