Table 2 A literature survey of the relationship between the presence of the luxS gene and QS-2 dependent behavior in bacterial species without a luxP- or a lsrB-gene homolog in their genome for which a metabolic role was hypothesized in at least one work.

From: Lack of genomic evidence of AI-2 receptors suggests a non-quorum sensing role for luxS in most bacteria
