UniProtKB - P19636 (EUTC_ECOLI)
Protein
Ethanolamine ammonia-lyase small subunit
Gene
eutC
Organism
Escherichia coli (strain K12)
Status
Functioni
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).
By similarity1 Publication2 PublicationsCaution
In strain MG1655 the eut operon is interrupted by the CPZ-55 prophage, encoding 9 genes situated between eutA and eutB, which are translated in the other direction. CPZ-55 may prevent expression of the eut operon in strain MG1655. Strain W3110 does not have this prophage element and should be able to express the operon.1 Publication

Cofactori
adenosylcob(III)alaminUniRule annotation4 PublicationsNote: Binds 1 AdoCbl between the large and small subunits, with 6 cofactors per holoenzyme.UniRule annotation1 Publication3 Publications
Activity regulationi
Inhibited by 5-adeninylpentylcobalamin (AdePeCbl), a cofactor analog (PubMed:19762342). Irreversibly inhibited during catalysis by cleavage of the Co-C bond of the cobalamin coenzyme (Probable) (PubMed:19762342). Reactivated by EutA, which probably involves an ATP-dependent cobalamin exchange (PubMed:15466038).1 Publication2 Publications
