Homogentisate dioxygenase (HGO) cleaves the aromatic ring during the metabolic degradation of Phe and Tyr. HGO deficiency causes alkaptonuria (AKU), the first human disease shown to be inherited as a recessive Mendelian trait. Crystal structures of apo-HGO and HGO containing an iron ion have been determined at 1.9 and 2.3 Å resolution, respectively. The HGO protomer, which contains a 280-residue N-terminal domain and a 140-residue C-terminal domain, associates as a hexamer arranged as a dimer…

Structural analysis reveals that this TK2203 protein shares the same fold and catalytic residues as other extradiol dioxygenases, strongly suggesting the same enzymatic activity.

Screening and molecular characterization of lethal mutations of human homogentisate 1, 2 dioxigenase

Systematic staged-screening of some sixty-five mutations showed that mutations, W60G, A122D and V300G are potentially related with the severity of AKU, and detailed analyses on molecular docking and molecular dynamics simulation of these mutants against the wild-type HGD reveal the loss of structural and molecular dynamic properties of the enzyme.

Structure and assembly of protocatechuate 3,4-dioxygenase

The X-ray structure determination of 3,4-PCD reveals the catalytic iron environment required for oxygenolytic cleavage of aromatic rings and also provides a novel holoenzyme assembly with cubic 23(T) symmetry and first examples of mixed β-barrel domains.

The molecular basis of alkaptonuria

The cloning of the human HGO gene is reported and it is established that it is the AKU gene, illustrating that HGO harbours missense mutations that cosegregate with the disease, and providing biochemical evidence that at least one of these missesense mutations is a loss–of–function mutation.

Evolutionary relationships among extradiol dioxygenases

Phylogenetic analyses indicate that the ancestral extradiol dioxygenase was a one-domain enzyme and that the two-domain enzymes arose from a single genetic duplication event.

Bovine liver homogentisicase: apoand reconstituted holoenzymes.

Bovine liver homogentisicase can exist in two forms which are interpreted as being apo-and holoenzymes, which are compared with respect to absorption spectrum, effects of reducing agents and pH on activity (or on reconstitution), stability, and molecular weight.

HGO consists of a single type of subunit with no intermolecular disulfide bridges and requires Fe2+ as a cofactor, which emphazises that the enzyme is familiar with the class of extradiol dioxygenases.
