EC Number: 3.2.1.21
Description Reaction Reference
Hydrolysis of terminal, non-reducing β-D-glucosyl residues with release of β-D-glucose.
EC Number: 3.2.1.45

Activator Comments
Ambroxol and NCGC607 increase GCase activity within lysosomes, but this effect is an indirect one. The compounds act as chaperones that improve GCase transport from the ER to lysosomes. Ambroxol binds to the GCase catalytic site, so has direct inhibitory potential, whereas NCGC607 has been determined to be noninhibitory [1].

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 [2]. Ambroxol acts as a molecular chaperone, and is predicted to offer disease modifying activity in GBA-mutant Parkinson's disease [4]. Targeting the GBA-alpha-synuclein (SNCA) pathway is also viewed as a novel mechanism that offers neuroprotective potential in Parkinson's disease [5].
