CC   -!- FUNCTION: Catalyzes the deamination of various vicinal amino-alcohols
CC       to oxo compounds. Allows this organism to utilize ethanolamine as the
CC       sole source of nitrogen and carbon in the presence of external vitamin
CC       B12. {ECO:0000255|HAMAP-Rule:MF_00601}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ethanolamine = acetaldehyde + NH4(+); Xref=Rhea:RHEA:15313,
CC         ChEBI:CHEBI:15343, ChEBI:CHEBI:28938, ChEBI:CHEBI:57603; EC=4.3.1.7;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00601};
CC   -!- COFACTOR:
CC       Name=adenosylcob(III)alamin; Xref=ChEBI:CHEBI:18408;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00601};
CC       Note=Binds between the large and small subunits. {ECO:0000255|HAMAP-
CC       Rule:MF_00601};
CC   -!- PATHWAY: Amine and polyamine degradation; ethanolamine degradation.
CC       {ECO:0000255|HAMAP-Rule:MF_00601}.
CC   -!- SUBUNIT: The basic unit is a heterodimer which dimerizes to form
CC       tetramers. The heterotetramers trimerize; 6 large subunits form a core
CC       ring with 6 small subunits projecting outwards. {ECO:0000255|HAMAP-
CC       Rule:MF_00601}.
CC   -!- SUBCELLULAR LOCATION: Bacterial microcompartment {ECO:0000255|HAMAP-
CC       Rule:MF_00601}.
CC   -!- SIMILARITY: Belongs to the EutC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00601}.
