The former is just before the promoter biology promoter , and the latter is just after the galE gene the first gene in the operon . Repression of gene expression works via binding of repressor molecules to the two operators. These repressors dimerize, creating a loop in the DNA. The loop as well as hindrance from the external operator prevent RNA polymerase from binding to the promoter, and thus prevent transcription genetics transcription . The gal operon of E. coli consists of 3 structural genes galE epimerase , galT galactose transferase , and galK galactokinase , which are transcribed from two overlapping promoters PG1 and PG2 upstream from galE . Regulation of the operon is complex since the GalE product, an epimerase that converts UDP galactose into UDP glucose, is required for the formation of UDP glucose for cell wall biosynthesis even when cells are not using galactose as a carbon energy source.
