Co-complex structure of the F4 fimbrial adhesin FaeG variant ac with llama single domain antibody V2

Structural highlights

4wen is a 2 chain structure with sequence from Escherichia coli and Lama glama. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

FAEG2_ECOLX K88 major fimbrial subunit. Fimbriae (also called pili), are polar filaments radiating from the surface of the bacterium to a length of 0.5-1.5 micrometers and numbering 100-300 per cell. They enable bacteria to colonize the epithelium of specific host organs.

Publication Abstract from PubMed

Enterotoxigenic Escherichia coli that cause neonatal and post-weaning diarrhea in piglets express F4 fimbriae to mediate attachment towards host receptors. Recently we described how llama single domain antibodies (VHHs) fused to IgA, produced in Arabidopsis thaliana seeds and fed to piglets resulted in a progressive decline in shedding of F4 positive ETEC bacteria. Here we present the structures of these inhibiting VHHs in complex with the major adhesive subunit FaeG. A conserved surface, distant from the lactose binding pocket, is targeted by these VHHs, highlighting the possibility of targeting epitopes on single-domain adhesins that are non-involved in receptor binding.

Structural insight in the inhibition of adherence of F4 fimbriae producing enterotoxigenic Escherichia coli by llama single domain antibodies.,Moonens K, Van den Broeck I, Okello E, Pardon E, De Kerpel M, Remaut H, De Greve H Vet Res. 2015 Feb 24;46(1):14. doi: 10.1186/s13567-015-0151-x.
