Peptidoglycolipid addressing protein

The Peptidoglycolipid Addressing Protein (GAP) Family^[1] is a member of the Lysine Exporter (LysE) Superfamily.^[2] It is listed as item 2.A.116 in the Transporter Classification Database.The mechanism of its action is not known, but this family has been shown to be a member of the LsyE superfamily. Therefore, these proteins are most likely secondary carriers.

The proposed generalized reaction catalyzed by members of the GAP family is:

PGL (in) → PGL (outer membrane).^[3]
