This entry represents a domain found in N-terminal in MFE-2 hydratase 2 and related enzymes. This domain is housing the cavity for the aliphatic acyl part of the substrate molecule. The flexibility of region within this domain plays a role in substrate binding in mammalian hydratase 2 [2].	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
