Description
Imported from IPR037143

The 4'-phosphopantetheinyl transferase domain superfamily of proteins transfer the 4'-phosphopantetheine (4'-PP) moiety from coenzyme A (CoA) to the invariant serine of pp-binding. This post-translational modification renders holo-ACP capable of acyl group activation via thioesterification of the cysteamine thiol of 4'-PP

. This superfamily consists of two subtypes: The ACPS type such as ACPS_ECOLI and the Sfp type such as SFP_BACSU. The structure of the Sfp type is known

, which shows the active site accommodates a magnesium ion. The most highly conserved regions of the alignment are involved in binding the magnesium ion.
