The capsule assembly protein Wzi Family [Function: Biogenesis/Secretion] Seed alignment | Full alignment | Pfam page | TC-DB page

This family consists of homologs to the wzi protein of E.coli. Wzi was found to be involved in the surface assembly of the Escherichia coli K30 group 1 capsule, participating in the translocation of group 1 capsular polysaccharide in co-operation with the wza complex. Wzi is an outer membrane monomeric 18-stranded ß-barrel protein. Homologs are also found in genera Klebsiella pneumoniae, Acinetobacter, Psychrobacter, Shewanella oneidensis, Rhodobacter sphaeroides, Idiomarina loihiensis and Microbulbifer degradans.
