None.

Description

Fumarylacetoacetase (EC:3.7.1.2; also known as fumarylacetoacetate hydrolase or FAH) catalyses the hydrolytic cleavage of a carbon-carbon bond in fumarylacetoacetate to yield fumarate and acetoacetate as the final step in phenylalanine and tyrosine degradation [PMID: 11154690]. This is an essential metabolic function in humans, the lack of FAH causing type I tyrosinaemia, which is associated with liver and kidney abnormalities and neurological disorders [PMID: 16602095, PMID: 9101289]. The enzyme mechanism involves a catalytic metal ion, a Glu/His catalytic dyad, and a charged oxyanion hole [PMID: 10508789]. FAH folds into two domains: an N-terminal domain SH3-like beta-barrel, and a C-terminal with an unusual fold consisting of three layers of beta-sheet structures [PMID: 10508789].
