Comments [?]

Function Catalyzes activation of the choline trimethylamine-lyase CutC under anaerobic conditions by generation of an organic free radical on a glycine residue, via an homolytic cleavage of S-adenosyl-L-methionine (SAM).
Catalytic activity RHEA:61976: glycyl-[protein] + reduced [flavodoxin] + S-adenosyl-L-methionine = 5'-deoxyadenosine + glycin-2-yl radical-[protein] + H(+) + L-methionine + semiquinone [flavodoxin]
case <FTGroup:1> and <FTGroup:2>
Cofactor [4Fe-4S] cluster
Note: Binds 2 [4Fe-4S] clusters. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine;
else
Cofactor [4Fe-4S] cluster
end case
Pathway Amine and polyamine metabolism; choline degradation.
Similarity Belongs to the organic radical-activating enzymes family.
