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].
