Protein Domain : Lipoprotein-releasing system transmembrane protein LolC/E IPR011925

Type  Family
Description  This entry describes the LolC protein, and its paralog LolE found in some species. These proteins are homologous to permease proteins of ABC transporters. In some species, two paralogs occur, designated LolC and LolE. In others, a single form is found and tends to be designated LolC [ ].The LolCDE complex releases lipoproteins from the inner membrane, thereby initiating lipoprotein sorting to the outer membrane. The LolCDE complex in Escherichia coli is composed of two copies of an ATPase subunit, LolD, and one copy each of integral membrane subunits LolC and LolE [ ]. TheLolCDE complex releases the lipoproteins in the periplasm, where they form a complex with LolA. The LolA-lipoprotein complex crosses the periplasm to reach the outer membrane, where LolB incorporates the lipoprotein into the outer membrane. LolA is involved in the interaction with membrane subunit LolC, whereas no interaction has been observed with LolE. This observations indicate that LolC and LolE may play different roles in the lipoprotein transfer despite their structural resemblance [ , ].
