[1] It is consistently found in the presumed 5' untranslated regions of sucA genes, which encode Oxoglutarate dehydrogenase enzymes that participate in the citric acid cycle.

Given this arrangement, sucA-II RNAs might regulate the downstream sucA gene.

This genetic arrangement is similar to the previously reported sucA RNA motif.

However, sucA-II RNAs are found only in bacteria classified within the genus Pseudomonas, whereas the previously reported motif is found only in betaproteobacteria.
