lsrB

Autoinducer 2-binding protein LsrB. Membrane channel protein. Part of the ABC transporter complex LsrABCD involved in autoinducer 2 (AI-2) import. Regulation of uptake and processing of the quorum-sensing AI-2. Binds AI-2 and delivers it to the LsrC and LsrD permeases (Probable). Share the same promoter with lsrA. In the absence of AI-2, repressed by LsrR. Induced by AI-2, via release of the LsrR repressor. In the absence of glucose, induced by cAMP-CRP by direct binding to the upstream region of the lsr promoter.

Usage and Biology

AI-2 “Consumer” was constructed by overexpressing the lsrACDB, lsrFG and lsrK genes in Bacillus amyloliquefaciens LL3.

This part is originated from Bacillus thuringiensis serovar thuringiensis str. IS5056.
