This domain has been identified in fungi and bacteria. 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].	Domain

The structure of beta-ketoacyl synthase is similar to that of the thiolase family (Pfam:PF00108) and also chalcone synthase. The active site of beta-ketoacyl synthase is located between the N and C-terminal domains. The N-terminal domain contains most of the structures involved in dimer formation and also the active site cysteine [1].	Domain

M ...	This entry includes a domain found in the central region of the acyltransferase domain (AT) from fungal type I fatty acid synthase (FAS, such as FAS1 from yeast) and mycobacteria, which have secondary-structure elements and sequence homology [1-5]. Mycobacterial fatty acid synthase (FAS) complex is an homohexameric multifunctional enzyme that catalyses the synthesis of fatty acid precursors of mycolic acids, the major components of the cell wall in Mycobacteria and play an important role in pathogenicity [6].

This entry represents the SBS domain (Six-Stranded Beta Sheet) of Fatty Acid Synthase (FAS) from Mycobacterium smegmatis and related proteins found in Actinomycetes. This domain plays important roles in protein assembly and stability. It is composed of a meander beta-sheet decorated with few helices [1].	Domain

The maoC gene is part of a operon with maoA which is involved in the synthesis of monoamine oxidase [1]. 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.	Domain
