in galactosialidosis fibroblasts also no mature beta-gal is found in the lysosomes but in these cells the presence of the monomeric form can be increased by leupeptin ( inhibition of proteolysis ) whereas addition of a partly purified 32 kda `` '' protective protein '' '' results in the restoration of high molecular weight beta-gal multimers in the lysosomes .
