Protein attributes

Sequence length	549 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (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 By similarity. HAMAP MF_01059
Catalytic activity	Alpha,alpha-trehalose + H2O = 2 D-glucose. HAMAP MF_01059
Pathway	Glycan degradation; trehalose degradation; D-glucose from alpha,alpha-trehalose: step 1/1. HAMAP MF_01059
Subunit structure	Monomer By similarity. HAMAP MF_01059
Subcellular location	Cytoplasm By similarity HAMAP MF_01059.
Sequence similarities	Belongs to the glycosyl hydrolase 37 family.
