| CoA-[4'-phosphopantetheine] + apo-[acyl-carrier protein] | assay with ACP substrates from Leishmania major (LmACP), Escherichia coli, Plasmodium falciparum, Mycobacterium tuberculosis, and Homo sapiens. The structure of the holo-acyl carrier protein of Leishmania major is similar to other type II ACPs, comprising a four-helix bundle, enclosing a hydrophobic core, but it displays a remarkably different phosphopantetheinyl transferase binding interface.
