Summary
EutBC deaminates amino-alcohols (ethanolamine) to oxo compounds (acetaldehyde) and ammonia. [More information is available at EcoGene: EG50007]. EutC codes for the smaller subunit, which is the probable catalytic subunit carrying the ethanolamine and adenosylcobalamin binding sites. [More information is available at EcoCyc: EG50007].
