The Preferential Synthesis of β-Galactosidase in Free

Abstract

Summary: The induced formation of -galactosidase in relation to overall protein synthesis in was examined under conditions where the enzyme inducer was required for growth. There was, initially, a substantial production of -galactosidase without any detectable increase in total cell protein. This phenomenon has been termed ‘preferential’ -galactosidase synthesis. The occurrence of preferential -galactosidase synthesis indicates that -galactosidase formation is a discrete event in cellular metabolism, and is not necessarily geared to overall cell growth. The data obtained also suggest that the carbon source(s) for preferential -galactosidase synthesis might be of endogenous origin.
