nhaA-II motifs are found in Caulobacterales.

nhaA-II motif RNAs likely function as cis-regulatory elements, in view of their positions upstream of protein-coding genes. nhaA-I RNAs typically occur upstream of genes that encode exchangers of sodium ions and protons. More rarely, they also exist upstream of methyltransferases that use S-adenosylmethionine as a donor.
