Abstract

β Galactosidase (EC 3.2.1.23), prepared from strains ML 308 and K12 3300 of E. coli, dissociated into an inactive monomer in the presence of Ag+. When such a monomer preparation is treated with excess of thiol an enzymically active dimer is formed in addition to an active tetramer. It is suggested that Ag+ may be of value in studies of other multimeric proteins as a mild dissociating agent.
