Bacterial murein precursor exporter

The bacterial murein precursor exporter (MPE) family (TC# 2.A.103) is a member of the cation diffusion facilitator (CDF) superfamily of membrane transporters. Members of the MPE family are found in a large variety of Gram-negative and Gram-positive bacteria and facilitate the translocation of lipid-linked murein (aka peptidoglycan) precursors. A representative list of proteins belonging to the MPE family can be found in the Transporter Classification Database.
