8.A.48 The Putative Auxiliary Aromatic Acid Exporter (AaeX) Family

The AaeX family (the DUF1656 family) includes many small proteins of 60 - 90 aas and 2 TMSs.  These proteins are associated with and encoded within operons encoding transporters of the AAE (TC# 2.A.85) Family.  Some members are annotated (probably incorrectly) FixA.
