Abstract
Investigation of the β-galactosidase activity of Escherichia coli B has confirmed the view that the access of β-galactosides to the intracellular site of enzyme activity is limited by a permeability barrier. Evidence presented indicates that passage of β-galactosides across this barrier is effected by the combined action of a process of physical diffusion and that of an enzyme-like transport system.Keywords
