E. coli ethanolamine ammonia lyase light chain

Partial trypsin digestion of this subunit (removing the first 28 residues) yields an active protein less susceptible to aggregation.

Catalyzes the deamination of various vicinal amino-alcohols to oxo compounds (PubMed:19762342). Ethanolamine ammonia-lyase (EAL) allows bacteria to utilize ethanolamine as the sole source of nitrogen and carbon in the presence of external vitamin B12. It is spontaneously inactivated by its substrate and reactivated by EutA (PubMed:15466038). Directly targeted to the BMC. May play a role in bacterial microcompartment (BMC) assembly or maintenance (By similarity).

Amine and polyamine degradation; ethanolamine degradation.

Belongs to the EutC family.
