Protein Family Models

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. [1]. 8647101.

This enzyme is proposed to act in the ring-opening step of phenylacetic acid degradation [1] which follows ligation of the acid with coenzyme A (by PaaF) and hydroxylation by a multicomponent non-heme iron hydroxylase complex (PaaGHIJK). Gene symbols have been standardized in [2]. This enzyme is related to aldehyde dehydrogenases and has domains which are members of the PF00171 and PF01575 families. This family includes paaN genes from Pseudomonas, Sinorhizobium, Rhodopseudomonas, Escherichia, Deinococcus and Corynebacterium. Another homology family (TIGR02288) includes several other species.
