Function
function
Catalyzes the deamination of various vicinal amino-alcohols to oxo compounds. Allows this organism to utilize ethanolamine as the sole source of nitrogen and carbon in the presence of vitamin B12.
Catalytic activity
- ethanolamine = acetaldehyde + NH4+
Cofactor
Note: Binds between the large and small subunits.
Pathway
Amine and polyamine degradation; ethanolamine degradation.

Interaction
Subunit
The basic unit is a heterodimer which dimerizes to form tetramers. The heterotetramers trimerize; 6 large subunits form a core ring with 6 small subunits projecting outwards.
