fadL
E. coli fatty acid transporter
Usage and Biology
The permeability of fatty acids across the cell membrane is very low because the outer layer of the outer membrane of Escherichia coli consists mainly of lipopolysaccharides and is the main barrier for the transport of hydrophobic compounds to Escherichia coli, so the bioconversion of fatty acids within the cell may be slow due to supply constraints. The expression level of fatty acid transporter fadL has a significant effect on the biotransformation of E. coli. It is an essential carrier for the transport of exogenous fatty acids, and its presence facilitates the transport of fatty acids across the outer membrane, especially those containing 10-18 C.

Experiment and result
BUCT-China overexpressed fadL gene in Escherichia coli, and verified by comparing the product yield obtained by overexpressing fadL and not overexpressing fadL gene. The results showed that the yield of polyhydroxyfatty acid lipid (PHFA) increased by nearly 1.7 times in engineering bacteria overexpressing fadL. These results indicate that the transporter protein expressed by fadL has a significant effect on the yield of PHFA.
