Purification and characterization of a sea squirt beta-galactosidase.

abstract：:Kinetic studies of the two beta-glucosidase isozymes, GB-1 and GB-2, which were from the culture filtrate of a phytopathogenic fungus Pyricularia oryzae, revaled that the latter isozyme was an allosteric protein with two substrate binding sites.
