Sucrose gradient centrifugation of the monomeric form (A1) of porcine spleen beta-galactosidase showed a pH-dependent equilibrium between monomer at neutral pH (pH 7.0) and dimer at acidic pH (pH 5.4-3.0), independent of ionic strength. While the oligomeric form (Ao), which was hardly dissociated under physiological conditions, was dissociated only with some protein denaturing agents into similar catalytic subunit to the A1. Both the A1 and Ao were equally active and stable at acidic pH, in the physiological condition inside lysosome (around pH 4.6).
