Dear Jfdwolff Maybe consider leaving that link into the Proteopedia page - it really shows the enzyme, Acid-beta-glucosidase, which when defective produces Gaucher's disease in a nice way, i.e. in 3D, please take a look at that page, and consider restoring the link, i.e. http://www.proteopedia.orgview_html.php?sq=&lang=&q=index.php/Acid-beta-glucosidase. n.b. the link can be gotten to simply by typing: Proteopedia Acid-beta-glucosidase Looking forward to hearing from you, with best regards, Joel L.
