Fumarylacetoacetate Hydrolase Domain Containing Protein 2B (FAHD2B)

FAHD2B belongs to the FAH family. May have hydrolase activity. Fumarylacetoacetate hydrolase is an enzyme which catalyzes the hydrolysis of 4-fumarylacetoacetate into fumarate and acetoacetate.The FAH gene provides instructions for making an enzyme called fumarylacetoacetate hydrolase. This enzyme is abundant in the liver and kidneys, and smaller amounts are found in many tissues throughout the body. Fumarylacetoacetate hydrolase is the last in a series of five enzymes needed to break down the amino acid tyrosine, a protein building block found in many foods. Specifically, fumarylacetoacetate hydrolase converts a tyrosine byproduct called fumarylacetoacetate into smaller molecules that are either excreted by the kidneys or used in reactions that produce energy.
