Short name: Porin_LamB

Family relationships

  • Porin, LamB type (IPR003192)


Maltoporin (LamB protein) forms a trimeric structure which facilitates the diffusion of maltodextrins across the outer membrane of Gram-negative bacteria. The membrane channel is formed by an antiparallel beta-barrel [PMID: 7824948]. The porin LamB family also includes porin BglH, which may be a sugar porin with a broad carbohydrate specificity, and sucrose porin [PMID: 1649946, PMID: 9437428].
