8.A.12 The ABC Bacteriocin Exporter Accessory Protein (BEA) Family

&9;The BEA family accesory proteins are small proteins of 127-174 amino acyl residues that function in conjunction with export porters of the ABC superfamily. They are found in Gram-positive bacteria and function in the export of bacteriocins. Without these accessory proteins, the ABC exporters are nonfunctional. BEA family proteins exhibit a single C-terminal, putative, transmembrane spanner.
