1.B.73.1.1
The outer membrane group 1 antigen capsule biogenesis/assembly protein, Wzi of 477 aas.  It forms an 18 stranded beta barrel, is a lectin, and plays a role in generating the end product of capsule assembly (Rahn et al. 2003). The 2.6 Å structure reveals long extracellular loops that block the barrel entrance while a helical bundle blocks the other end of the pore (Bushell et al. 2013). Also functions as a passive bidirectional water specific porin (Sachdeva et al. 2016Sachdeva et al. 2016).
