Note(s): rdlB is one of a set of four rdl genes, one of which (rdlD) has been shown to code for the antisense regulatory RNA component of a toxin-antitoxin pair. All of the rdl genes are associated with a matched ldr gene Kawano M,2002. cDNA clones of RdlB RNA have been obtained Kawano M,2005.
Overexpression of RdlB decreases swarming motility and curli expression Bak G,2015.
