The Poly Acetyl Glucosamine Porin (PgaA) Family [Function: Biogenesis / Secretion] Seed alignment | Full alignment | TC-DB page

PgaA controls the translocation of de-N-acetylated poly-b-1,6-N-acetyl-d-glucosamine (dPNAG) polymer into the bacterial outer membrane. dPNAG is crucial for biofilm adhesion and has an important role in the maintenance and development of biofilms integration for various bacterial species. PgaA ß barrel domain (513-807) consists of 16 antiparallel transmembrane ß sheets with b1 and b16 strands interlocking.
