General annotation (Comments)

Function	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 activity	ATP + L-serine = diphosphate + L-serine-adenylate.
Cofactor	Binds 1 phosphopantetheine covalently.
Pathway	Siderophore biosynthesis; enterobactin biosynthesis.
Subunit structure	EntB, entD, entE, and entF form a multienzyme complex called enterobactin synthase. EntF acts as a catalytic monomer.
Induction	Transcriptionally regulated by iron and the fur protein.
Post-translational modification	4'-phosphopantetheine is transferred from CoA to a specific serine of apo-entF by entD. Holo-entF so formed is then acylated with seryl-AMP.
Sequence similarities	Belongs to the ATP-dependent AMP-binding enzyme family. EntF subfamily. Contains 1 acyl carrier domain.
