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.
Examples:
TC#	Name	Organismal Type	Example
8.A.48.1.1	DUF1656 protein, YdhI or AaeX₁ of 78 aas and 2 TMSs. It's gene is in an operon with a gene encoding YdhK, a member of the ArAE family (2.A.85) in the gene order ydhI - ydhJ (MFP; 8.A.1) - ydhK.	Proteobacteria	YdhI of E. coli

8.A.48.1.2	AaeX homologue of 90 aas and 2 TMSs	Proteobacteria	AaeX₂ of E. coli

8.A.48.1.3	AaeX (YhcR or YdhI) homologue of 67 aas and 2 TMSs	Proteobacteria	AaeX of E. coli

8.A.48.1.4	AaeX homologue of 67 aas and 2 TMSs	Proteobacteria	AaeX of Azospirillum brasilense

8.A.48.1.5	AaeX of 67 aas and 2 TMSs.	Proteobacteria	AaeX of Pectobacterium atrosepticum

8.A.48.1.6	AaeX of 66 aas and 2 TMSs	Proteobacteria	AaeX of Pseudomonas syringae
