1.B.85.1.1
The pellicle exporting porin of 1193 aas and 1 N-terminal α-helical TMS with up to 48 β-strands, PelB. The porin is in the N-terminal domain while the 19 predicted periplasmic TPRs are C-terminal. These repeats bind PelA, a periplasmic hydrolase (see the family description and Marmont et al. 2017). PelA and PelB together form a modification and secretion complex essential for Pel polysaccharide-dependent biofilm formation in P. aeruginosa (Marmont et al. 2017).
