Stimulation of galactokinase synthesis in Escherichia coli by adenosine 3',5'-cyclic monophosphate.
Adenosine 3',5'-cyclic monophosphate (cyAMP) stimulates the rate of synthesis of galactokinase in glycerol-grown Escherichia coli both when production of the enzyme is induced by d-fucose and when it is repressed by glucose in the presence of inducer. cyAMP also stimulates the synthesis of galactokinase in constitutive strains B78A (R(-)) and R10 (O(c)), and overcomes the transient repression of galactokinase synthesis caused by glucose.
