The sucA RNA motif is a putative regulatory element found upstream of the sucAB-lpdA genes in bacteria of the order Burkholderiales of Betaproteobacteria [17621584]. The products of these three genes form an enzyme complex catalyzing synthesis of succinyl-CoA from 2-oxoglutarate, a critical reaction in the citric acid cycle. The sucA RNA motif has stems that overlap th ribosomal binding site of the first gene, suggesting it can probably function as a cis-acting riboswitch. However, the function of this RNA motif remains unknown.
