Protein

Enterobactin synthase component F

Gene

entF

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Activates the carboxylate group of L-serine via ATP-dependent PPi exchange reactions to the aminoacyladenylate, preparing that molecule for the final stages of enterobactin synthesis. Holo-EntF acts as the catalyst for the formation of the three amide and three ester bonds present in the cyclic (2,3-dihydroxybenzoyl)serine trimer enterobactin, using seryladenylate and acyl-holo-EntB (acylated with 2,3-dihydroxybenzoate by EntE).

Catalytic activityi

ATP + L-serine = diphosphate + L-serine-adenylate.

Cofactori

pantetheine 4'-phosphateNote: Binds 1 phosphopantetheine covalently.
