Enterobacteria greA leader

The Enterobacteria greA leader is a putative attenuator element identified by bioinformatics within bacteria of the γ-proteobacterial Enterobacteriales order.^[1] It is located upstream of the rnk gene, encoding a transcription elongation factor, and presents a Rho-independent terminator at the 3' end. This RNA is presumed to operate as a non-coding leader, which regulatory mechanism remains to be elucidated.^[1] The short abortive form of the greA transcript may also play a role as an independent sRNA: Potrykus et al. have shown that its overexpression leads to the repression of several genes.^[2] The motif might be related to other rnk leaders such as the Pseudomonas rnk leader and the Enterobacteria rnk leader.^[1]
