Neae-Nb3
Neae-Nb is a type of nanobody, which contains variable domains of camelid heavy-chain antibodies, that can be expressed on bacterial surfaces due to their small size (~125 amino acids) and stability under a variety of conditions The combination between the single-domain structure and the intimin autotransporter allows the entirety of a highly specific, cell surface-bound adhesin to be encoded as a single fusion protein. Neae-Nb will specifically adhere to a corresponding antigen via the Nb-Ag interaction, which can form the adhesins and control morphology and patterning of multicellular assemblies.

Usage and Biology
Nanobodies are the recombinant variable domains of heavy-chain-only antibodies, with many unique properties such as small size, excellent solubility and superior stability. This nanobody domain interacts with specific antigen through antigen nanobody interactions and can be used for cell-cell adhesion and bacterial surface display with a high adhesion stability.The CDR(Complementarity-determining region) domain of the nanobodies determine their antigen-recognition specificity.In our experiment, Nb3 displayed on the outer membrane specifically interacts with Ag3 on the OlpB-Ag3 fusion construct (BBa_K4275013), promoting the immobilization of cellulosome complexes onto the surface of the bacteria.
