Cytoplasmic trehalase (P62601)

Identification
Name:Cytoplasmic trehalase
Synonyms:
  • Alpha,alpha-trehalase
  • Alpha,alpha-trehalose glucohydrolase
Gene Name:treF
Enzyme Class:
Biological Properties
General Function:Involved in catalytic activity
Specific 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
Cellular Location:Cytoplasm
