EC Number:
Description Reaction Reference
Hydrolysis of terminal, non-reducing β-D-glucosyl residues with release of β-D-glucose.
EC Number:
Description Reaction Reference
D-glucosyl-N-acylsphingosine + H2O <=> D-glucose + N-acylsphingosine
Gene Expression and Pathophysiology Comments
Uniprot and OMIM provide detailed information on the GBA mutations that are associated with pathophysiological conditions including Gaucher's disease and Parkinson's disease.
General Comments
Ambroxol (PubChem CID 2132) is reported to rescue defective glucocerebrosidase activity in GBA-mutant Parkinson's disease cells [1]. Ambroxol acts as a molecular chaperone, and is predicted to offer disease modifying activity in GBA-mutant Parkinson's disease [2]. Targeting the GBA-alpha-synuclein (SNCA) pathway is also viewed as a novel mechanism that offers neuroprotective potential in Parkinson's disease [3].
