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}.
