Family 2.A.66 - The Multi Antimicrobial Extrusion Family

Family ID: 52642
The MATE family includes several sequenced members from bacteria
and yeast. These proteins include a functionally characterized
multidrug efflux system from Vibrio parahaemolyticus,NorM, and
several homologues from other closely related bacteria that function
by a drug:Na+antiport mechanism, a putative ethionine resistance
protein of Saccharomyces cerevisiae,and the functionally uncharacterized
DNA damage-inducible protein F (DinF) of E. coli. The bacterial
proteins are of about 450 amino acyl residues in length and exhibit
12 putative TMS. They arose by an internal gene duplication event
from a primordial 6 TMS encoding genetic element. The yeast proteins
are larger (up to about 700 residues) and exhibit about 12 TMSs.
