Fumarylacetoacetate hydrolase domain-containing protein 1, also known as FLJ36880 protein, is an enzyme that in humans is encoded by the FAHD1 gene on chromosome 16.[1]


Structure

The FAHD1 gene encodes for a 24-kDa protein that is localized to the mitochondrion and belongs to the fumarylacetoacetate hydrolase family of proteins.[2] The structure of FAHD1 has been resolved using X-ray crystallography at 2.2-Å resolution. The overall structure is similar to the C-terminal domain of the bifunctional enzyme HpcE from Escherichia coli C, fumarylacetoacetate hydrolase from Mus musculus and to YcgM (Apc5008) from E. coli 1262.[2] A number of conserved amino acids including Asp-102 and Arg-106 of FAHD1 appear to be important for its catalytic activity.[3]

Function

The FAHD1 protein has been shown to function as an oxaloacetate decarboxylase in eukaryotes.[4] The FAHD1 protein probably also functions as an acylpyruvase, having been shown to catalyze the hydrolysis of acetylpyruvate and fumarylpyruvate in in vitro experiments.[2] Mg(2+) was required for maximal enzyme activity.[3]
