Glycosyl hydrolases family 28. Glycosyl hydrolase family 28 includes polygalacturonase EC:3.2.1.15 as well as rhamnogalacturonase A(RGase A), EC:3.2.1.-. These enzymes is important in cell wall metabolism.

Na+-driven multidrug efflux pump [Defense mechanisms]

Subfamily of the multidrug and toxic compound extrusion (MATE)-like proteins similar to Vibrio cholerae NorM. The integral membrane proteins from the MATE family are involved in exporting metabolites across the cell membrane and are responsible for multidrug resistance (MDR) in many bacteria and animals. This subfamily includes Vibrio cholerae NorM and functions most likely as a multidrug efflux pump, removing xenobiotics from the interior of the cell. The pump utilizes a cation gradient across the membrane to facilitate the export process. NorM appears to bind monovalent cations in an outward-facing conformation and may subsequently cycle through an inward-facing and outward-facing conformation to capture and release its substrate.

putative efflux protein, MATE family. The Multi Antimicrobial Extrusion (MATE) Family (TC 2.A.66) The MATE family consists of probable efflux proteins including a functionally characterized multi drug efflux system from Vibrio parahaemolyticus, a putative ethionine resistance protein of Saccharomyces cerevisiae, and the functionally uncharacterized DNA damage-inducible protein F (DinF) of E. coli. These proteins have 12 probable TMS [Transport and binding proteins, Other].

Eukaryotic members of the multidrug and toxic compound extrusion (MATE) family. The integral membrane proteins from the MATE family are involved in exporting metabolites across the cell membrane and are responsible for multidrug resistance (MDR) in many bacteria and animals. MATE has also been identified as a large multigene family in plants, where the proteins are linked to disease resistance. A number of family members are involved in the synthesis of peptidoglycan components in bacteria. This subfamily, which is restricted to eukaryotes, contains vertebrate solute transporters responsible for secretion of cationic drugs across the brush border membranes, yeast proteins located in the vacuole membrane, and plant proteins involved in disease resistance and iron homeostatis under osmotic stress.
