Protein Family Models

MlaE is a permease which in E. coli is a component of the Mla pathway, an ABC transport system that functions to maintain the asymmetry of the outer membrane [1]. In Swiss:Q7DD59 it is involved in L-glutamate import into the cell [2]. In Swiss:Q8L4R0 it is involved in lipid transfer within the cell [2]. [1]. 19383799.

lipid asymmetry maintenance ABC transporter permease subunit MlaE is the transmembrane subunit (TM) found in periplasmic binding protein (PBP)-dependent ATP-binding cassette (ABC) transporter MlaFEDB, which is involved in a phospholipid transport pathway that maintains lipid asymmetry

This HMM describes a subfamily of ABC transporter permease subunits. One member of this family has been associated with the toluene tolerance phenotype of Pseudomonas putida, another with L-glutamate transport, another with maintenance of lipid asymmetry. Many bacterial species have one or two members. The Mycobacteria have large paralogous families included in the DUF140 family but excluded from this subfamily on based on extreme divergence at the amino end and on phylogenetic and UPGMA trees on the more conserved regions.
