ABSTRACT:
A method for labeling acyl carrier protein (ACP) fusion proteins with a wide variety of different labels is disclosed. The method relies on the transfer of a label from a coenzyme A type substrate to an ACP fusion protein using a holo-acyl carrier protein synthase (ACPS) or a homologue thereof. The method allows detecting and manipulating the fusion protein, both in vitro and in vivo, by attaching molecules to the fusion proteins that introduce a new physical or chemical property to the fusion protein. Examples of such labels are, among others, spectroscopic probes or reporter molecules, affinity tags, molecules generating reactive radicals, cross-linkers, ligands mediating protein-protein interactions or molecules suitable for the immobilization of the fusion protein.
