From: Premature terminator analysis sheds light on a hidden world of bacterial transcriptional attenuation
A possible attenuator based on bacterial interspersed mosaic elements (BIMEs). A conserved element found before the gatY, rbfA and cvpA genes in Enterobacteria, corresponding to BIMEs. Blue frames indicate terminators, black frames indicate possible anti-terminators. Conservation of these repeats in sequence and position argues for their utilization as attenuator elements.
