We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

==Crystal structure of the long-chain fatty acid transporter FadL==
-
The mechanisms by which hydrophobic molecules, such as long-chain fatty, acids, enter cells are poorly understood. In Gram-negative bacteria, the, lipopolysaccharide layer in the outer membrane is an efficient barrier for, fatty acids and aromatic hydrocarbons destined for biodegradation. We, report crystal structures of the long-chain fatty acid transporter FadL, from Escherichia coli at 2.6 and 2.8 angstrom resolution. FadL forms a, 14-stranded beta barrel that is occluded by a central hatch domain. The, structures suggest that hydrophobic compounds bind to multiple sites in, FadL and use a transport mechanism that involves spontaneous, conformational changes in the hatch.
