| Short Name | LsrA |
| description | LsrA is part of the ABC transporter complex LsrABCD that imports autoinducer 2 (AI-2), a protein that functions in interspecies cell-cell communication in bacteria. LsrA is responsible for energy coupling to the transport system [].AI-2 is synthesised via theenzyme LuxS and can induce transcription of the Lsr (LuxS regulated) operon (lsrACDBFGE) [, ]. The first four genes of the operon, lsrACDB, encode components of the ATP-binding cassette transporter, whereas the remaining two are required for the modification of AI-2 following internalisation []. |
