[https://www.uniprot.org/uniprot/FADL_ECOLI FADL_ECOLI] Involved in translocation of long-chain fatty acids across the outer membrane. It is a receptor for the bacteriophage T2. FadL may form a specific channel.

== Publication Abstract from PubMed ==
 +
Ligand-gated channels, in which a substrate transport pathway is formed as a result of the binding of a small-molecule chemical messenger, constitute a diverse class of membrane proteins with important functions in prokaryotic and eukaryotic organisms. Despite their widespread nature, no ligand-gated channels have yet been found within the outer membrane (OM) of Gram-negative bacteria. Here we show, using in vivo transport assays, intrinsic tryptophan fluorescence and X-ray crystallography, that high-affinity (submicromolar) substrate binding to the OM long-chain fatty acid transporter FadL from Escherichia coli causes conformational changes in the N terminus that open up a channel for substrate diffusion. The OM long-chain fatty acid transporter FadL from E. coli is a unique paradigm for OM diffusion-driven transport, in which ligand gating within a beta-barrel membrane protein is a prerequisite for channel formation.
