    I guess proteases have a very broad spectrum of substrates while glycosidases are very specific? Is that correct?

    You are right, but what I was getting at is that lysosomal storage disease are mainly caused by deficiencies in glycosidase enzymes and not proteases. I thought that the reason for that would be that glycosidases work 1 enzyme 1 substrate, while proteases are more generally active. If you are deficient in a proteases, other proteases would still be able to digest the accumulating substrate. I guess?

    Sorry,

    I totally misread your question there.:frown:
    I am not familiar with the lysosomal storage disease or glycosidases so much either, but I do know that proteases contain the potential to be quite specific based on the amino acid side chains that are contained within the peptide. Don't know if that helps at all, but hopefully it does.:smile:
