Large intergenic cruciform-like supermotifs in the Lactobacillus plantarum genome.

Abstract

Twenty-four Lactobacillus plantarum supermotifs (LPSMs) with lengths from approximately 800 to 1,000 nucleotides were identified in the L. plantarum genome. LPSMs were conserved in other L. plantarum strains but not in other species. Secondary structure analysis predicted that LPSMs may fold into cruciform-like structures. Preliminary experiments indicate that the LPSMs are transcribed.
