UniProtKB - P48016 (ATH1_YEAST)
Protein
Periplasmic acid trehalase ATH1
Gene
ATH1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Functioni
Periplasmic acid trehalase that catalyzes hydrolysis of the disaccharide trehalose and required for growth on trehalose as carbon source (PubMed:7502577, PubMed:8647289, PubMed:19703229, PubMed:8764988).
Growth on trehalose is strictly respiratory (By similarity).
By similarity4 PublicationsCaution
The functional relevance of vacuolar localization is disputed.2 Publications

- Periplasm By similarity
Note: May exist in the periplasm either as a membrane-bound or as a free protein (By similarity). Vacuolar localization is dependent on the multivesicular body (MVB) sorting pathway (PubMed:17475771). Vacuolar localization appears to be associated with its degradation (PubMed:19703229).By similarity2 Publications
