A molecular cloning strategy has ben designed to isolate the gene that encodes the small cytoplasmic RNA (scRNA) component of bacterial signal recognition particles. Using this strategy a putative Listeria monocytogenes scRNA lambda gt11 recombinant clone was isolated. A previously described complementation assay developed to genetically select functional homologues of 4.5S RNA and scRNA of bacteria confirmed that the lambda gt11 recombinant clone isolated encoded for the scRNA from L. monocytogenes. A secondary structure for this scRNA is proposed and a phylogenetic comparison of the 276 base L. monocytogenes scRNA with previously characterised Gram-positive bacterial scRNAs is also presented.
