Sequential appearance of the galactose enzymes in E. coli

Molecular and General Genetics MGG Aims and scope Submit manuscript

Summary

Upon induction, the three galactose enzymes appear in the order epimerase, transferase, kinase. Introduction of an amber mutation into the transferase gene seems to shorten the time interval between addition of inducer and the appearance of kinase. The time of appearance of epimerase is not influenced by amber mutations in the transferase gene.
