Posttranslational Modification	Comment	Organism
proteolytic modification	in normal cells an 84000 Da precursor is processed first to an intermediate form of higher molecular weight and then to a 64000 Da mature enzyme. In one case of GM1-gangliosidosis a precursor of abnormally high molecular weight is observed, no further processing occurs to the 88000 Da enzyme form	Homo sapiens
