This post-translational modification renders holo-ACP capable of acyl group activation via thioesterification of the cysteamine thiol of 4'-PP [1]. This superfamily consists of two subtypes: The ACPS type such as Swiss:P24224 and the Sfp type such as Swiss:P39135. The structure of the Sfp type is known [3], which shows the active site accommodates a magnesium ion. The most highly conserved regions of the alignment are involved in binding the magnesium ion.

To be catalytically competent, the FAS must be activated by a posttranslational modification of the central acyl carrier domain (ACP) by an intrinsic phosphopantetheine transferase (PPT) [1].

It is found in fatty acid synthase beta subunit from fungi, including Fas1 from yeasts and aflB from Aspergillus parasiticus. This is an inserted helical domain, whose function is not clear, and is found together with the MaoC-like domain (Pfam:PF01575) and the acyltransferase domain (Pfam:PF00698) [1]. Fas1 is a fatty acid synthetase that catalyses the formation of long-chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH [2]. AflB is part of the gene cluster that mediates the biosynthesis of aflatoxins [3].
