Pal

Structure

Pal is a lipoprotein which is anchored in the outer membrane. Synthesised as a precursor of 173 amino acids, it contains a signal sequence including an LVAC motif.

Pal forms a complex with TolB (see TolB)

Function

During translocation, signal peptidase II cleaves the LVAC motif, and the localisation of Pal is dependent on the Lol protein system.
