Alkane channel protein
The alkL protein is an alkane channel protein that comes from Pseudomonas Oleovorans. Its function is mainly to import medium to long chain alkanes into the cell. In Gram-negative cells, such as Escherichia coli and Shewanella oneidensis, import of medium to long chain alkanes is inhibited by the cell's lippopolysaccharide layer. The alkL protein's extracellular domain penetrates this layer and binds to alkane molecules with high affinity. Once the alkane has been bound, it is transported through the hydrophobic core of the alkL protein, thus bypassing the lipopolysaccharide layer. The alkane then enters the periplasm of the cell, where it can then diffuse into the cytoplasm. According to literature, the alkL protein is toxic when overexpressed and may inhibit host cell growth.
