Expressioni

Inductioni

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.2 Publications

Interactioni

Subunit structurei

The complex is composed of two ATP-binding proteins (LsrA), two transmembrane proteins (LsrC and LsrD) and a solute-binding protein (LsrB).Curated

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
