The Alginate Export Porin (algE) Family [Function: Biogenesis/Secretion] Seed alignment | Full alignment in OMPdb | |
Proteins of the AEP family are believed to export alginate (an acidic polysaccharide), across the outer membrane of Gram-negative bacteria. These proteins span the outer membrane forming a large ß-barrel comprised of 18 beta sheets, as the 3D structure of one of the family's members suggests. | |
