1.B.54.1.8









The ZirS/T (ZirS (276 aas)) is the putative exoprotein passenger domain, but it shows no sequence similarity to passenger domains of other Int/Inv family members. ZirT (660 aas) is the outer membrane β-barrel postulated transporter (Gal-Mor et al., 2008).

Bacteria
Pseudomonadota
ZirST of Salmonella enterica
ZirS β-barrel domain protein (Q8ZP79)
ZirT (Q8ZP78)
1.B.54.1.9









Putative outer membrane porin of 464 aas, YchO.

Bacteria
Pseudomonadota
YchO of E. coli
1.B.54.1.10









"Inverse" autotransporter (IAT) of 2,358 aas, YeeJ.  Functions in adhesion and biofilm formation.  It contains a LysM domain that interacts with peptidoglycan and thus assists in localization to the outer membrane. Polynucleotide Phosphorylase PNPase is a repressor of yeeJ transcription (Martinez-Gil et al. 2017).

Bacteria
Pseudomonadota
YeeJ of E. coli
