The crystal structure of EutN contains a central five-stranded beta-barrel, with an alpha-helix at the open end of this barrel (PDB:2HD3). The structure also contains three additional beta-strands, which help the formation of a tight hexamer, with a hole in the center. this suggests that EutN forms a pore, with an opening of 26 Angstrom in diameter on one face and 14 Angstrom on the other face [2]. EutN is involved in the cobalamin-dependent degradation of ethanolamine [1].	Domain
