Ascorbate oxidase

Acid ascorbic (vitamin C, AA), paracetamol (acetaminophene hay N-acetyl-paminophenol, PA) và caffein (CA) là ba thành phần ch yếu trong các loại thuốc giảm đau, hạ sốt như Panadol, Hapacol,...AA là một loại vitaminn đóng vai quan trọng trong tế bào động vật có vú, nếu thiếu vitamin C cơ thể sẽ mất dần sức đề kháng và có nguy cơ dẫn tới tử vong.

A phylogenetic analysis of more than 350 multicopper oxidases (MCOs) from fungi, insects, plants, and bacteria provided the basis for a refined classification of this enzyme family into laccasessensu stricto (basidiomyc-etous and ascomycetous), insect laccases, fungal pigment MCOs, fungal ferroxidases, ascorbate oxidases, plant laccase-like MCOs, and bilirubin oxidases.

The last step of the biosynthesis ofl-ascorbic acid (vitamin C) in plants and animals is catalyzed by l-gulono-1,4-lactone oxidoreductases, which use bothl-gulono-1,4-lactone and l-galactono-1,4-lactone as substrates. l-Gul-ono-1,4-lactone oxidase is missing in scurvy-prone, vitamin C-deficient ani-mals, such as humans and guinea pigs, which are also highly susceptible to tuberculosis.

The possible presence of dimeric unfolding intermediates might offer a clue to understanding the relationship between tertiary and quaternary structure formation in dimers. Ascorbate oxidase is a large dimeric enzyme that dis-plays such an intermediate along its unfolding pathway.

Ascorbate oxidase (AAO) is a large, multidomain, dimeric protein whose folding⁄unfolding pathway is characterized by a complex, multistep pro-cess. Here we used fluorescence correlation spectroscopy to demonstrate the formation of partially folded monomers by pH-induced full dissociation into subunits.
