Comments
[?]
| FUNCTION | Hydrolyzes trehalose to glucose. Could be involved, in cells returning to low osmolarity conditions, in the utilization of the accumulated cytoplasmic trehalose, which was synthesized in response to high osmolarity. |
| CATALYTIC ACTIVITY | Reaction=alpha,alpha-trehalose + H2O = alpha-D-glucose + beta-D- glucose; Xref=Rhea:RHEA:32675, ChEBI:CHEBI:15377, ChEBI:CHEBI:15903, ChEBI:CHEBI:16551, ChEBI:CHEBI:17925; EC=3.2.1.28; |
| PATHWAY | Glycan degradation; trehalose degradation; D-glucose from alpha,alpha-trehalose: step 1/1. |
| SUBUNIT | Monomer. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| SIMILARITY | Belongs to the glycosyl hydrolase 37 family. |
