Summary:
Aryl carrier proteins (ArCP) are a common component of non-ribosomal peptide synthetase (NRPS) complexes. The protein is expressed in the inactive apo form and the essential prosthetic group 4'-phosphopantetheine must be post-translationally attached to a conserved serine residue by the action of a phosphopantetheinyl transferase.

an <i>apo</i>-[aryl-carrier protein] compound structure

Child Classes: a 3-hydroxy-4-methyl-anthranilyl-L-threonyl-D-valyl-[AcmD acyl-carrier protein] (0), an apo-AsbD acyl-carrier protein (1), an apo-[AcmD acyl-carrier protein] (1), an apo-[EntB isochorismatase/aryl-carrier protein] (1), an NRPS containing an [aryl-carrier-protein] domain (0)

Alternative forms of an apo-[aryl-carrier protein]: a holo-[aryl-carrier protein]

SMILES: C(O)C(N[an aryl-carrier protein])C(=O)[an aryl-carrier protein]
