Transcription unit          
Name: ilvLXG_1G_2MEDA
Synonym(s): ilvGMEDA, ilvLGGMEDA, ilvLGMEDA, ilvLG_1G_2MEDA
Gene(s): ilvL, ilvX, ilvG, ilvM, ilvE, ilvD, ilvA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The ilvLGMEDA operon, which codes for four of the five enzymes required for isoleucine and valine biosynthesis, is primarily regulated by attenuation in response to the abundance of the end products of those pathways 6252193. It is also regulated by transcriptional regulators IHF and Lrp.
