    Protein Summary

    The gene LMOf2365_1185 (also known as eutB) from Listeria monocytogenes 4b f2365 encodes ethanolamine ammonia-lyase large (alpha) subunit (EutB) PF06751 COG4303.  The protein belongs to the class of alpha and beta (a+b) proteins and adopts a TIM beta/alpha-barrel fold type SCOP51350.  Ethanolamine ammonia-lyase (alternative name: ethanolamine deaminase) EC: is the enzyme which catalyzes the following reaction: ethanolamine <=> acetaldehyde + NH(3).  It requires cobalamin as a cofactor.  The enzyme enables bacteria to survive on small organic molecules such as ethanolamine as the sole source for carbon and nitrogen.
