General annotation (Comments)

Function	Each of the constituent amino acids of the tripeptide acv are activated as aminoacyl-adenylates with peptide bonds formed through the participation of amino acid thioester intermediates.
Catalytic activity	L-2-aminohexanedioate + L-cysteine + L-valine + 3 ATP + H2O = N-(L-5-amino-5-carboxypentanoyl)-L-cysteinyl-D-valine + 3 AMP + 3 diphosphate.
Cofactor	Binds 3 phosphopantetheines covalently.
Pathway	Antibiotic biosynthesis; penicillin G biosynthesis; penicillin G from L-alpha-aminoadipate and L-cysteine and L-valine: step 1/3.
Sequence similarities	Belongs to the ATP-dependent AMP-binding enzyme family. Contains 3 acyl carrier domains.
