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].

Divergence of the N- and C- monomers in higher eukaryotes has led to two distinct domains, this one and MaoC_dehydratas. However, in order to function as an enzyme both are required together.

The MaoC protein is found to share similarity with a wide variety of enzymes; estradiol 17 beta-dehydrogenase 4, peroxisomal hydratase-dehydrogenase-epimerase, fatty acid synthase beta subunit. Several bacterial proteins that are composed solely of this domain have (R)-specific enoyl-CoA hydratase activity [2]. This domain is also present in the NodN nodulation protein N.

FAS is a homo-hexameric enzyme that catalyzes synthesis of fatty acid precursors of mycolic acids. This domain is composed of dimerization module 1 (DM1) and four-helix bundle (4HB), both of which are conserved parts of the acetyl transferase [1].

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].
