an aromatic primary alcohol + O2 = an aromatic aldehyde + H2O2
a sequential mechanism in which O2 reacts with reduced enzyme before release of the aldehyde product, the AAO reductive half-reaction is essentially irreversible and rate limiting during catalysis, a synchronous mechanism in which hydride transfer from substrate alpha-carbon to FAD and proton abstraction from hydroxyl occur simultaneously, reaction mechanism, overview. The AAO catalytic mechanism proceeds via electrophilic attack and direct transfer of a hydride to the flavin

modeling protein-ligand recognition mechanisms, substrate diffusion into the AAO active site, two conserved histidine residues, His502 and His546, are involved in catalysis, structure-function analysis, overview
an aromatic primary alcohol + O2 = an aromatic aldehyde + H2O2
two conserved histidine residues, His502 and His546, are involved in catalysis and play roles in the two half-reactions, with a stronger histidine involvement in the reductive than in the oxidative half-reaction. His502 is the catalytic base in the AAO reductive half-reaction. The His502 proton transfer does not limit the oxidative half-reaction, stereoselective hydride transfer.

physiological function
-
the enzyme is part of the extracellular enzymatic machinery of the fungus to degrade lignin. The secreted, extracellular oxidase generates H2O2 for extracellular peroxidases. O2 activation by Pleurotus eryngii AAO takes place during the redox-cycling of 4-methoxylated benzylic metabolites secreted by the fungus. AAO provides a continuous supply of H2O2 by redox cycling phenolic benzylic alcohol compounds, in collaboration with mycelium dehydrogenases

physiological function
the enzyme is involved in the degradation of 5-hydroxymethylfurfural. Two enzymes groups, which belong to the ligninolytic system, aryl-alcohol oxidase and a dehydrogenase, are involved in this process
physiological function
-
aryl-alcohol oxidase generates H2O2 for lignin degradation at the expense of benzylic and other Pi system-containing primary alcohols, which are oxidized to the corresponding aldehydes; the enzyme is involved in lignin degradation. Within this multienzymatic process, which enables the recycling of carbon fixed by photosynthesis in land ecosystems, AAO reduces O2, providing the H2O2 required by ligninolytic peroxidases to oxidize the recalcitrant lignin polymer

additional information
-
structure-function relationship and analysis, overview. His502 activates the alcohol substrate by proton abstraction. Alcohol docking at the buried AAO active site results in only one catalytically relevant position for concerted transfer, with the pro-R alpha-hydrogen at distance for hydride abstraction, the enzyme shows hydride-transfer stereoselectivity

-
docking of 4-methoxybenzyl alcohol at the buried crystal active site, and quantum mechanical/molecular mechanical study, overview
additional information
-
AAO shows a buried active site connected to the solvent by a hydrophobic funnel-shaped channel, with Phe501 and two other aromatic residues forming a narrow bottleneck that prevents the direct access of alcohol substrates, while O2 has access to the active site following this channel. The side chain of Phe501, contiguous to the catalytic His502 in AAO, helps to position O2 at an adequate distance from flavin C4a (and His502Nepsilon). Phe501 substitution with a bulkier tryptophan residue results in an increase in theO2 reactivity of this flavoenzyme, free diffusion simulations of O2 inside the active-site cavity of AAO, the O2 reactivity of AAO decreases when the access channel is enlarged and increases when it is constricted by introducing a tryptophan residue, overview
additional information
-
residue 91 lies in the flavin attachment loop motif, and it is a highly conserved residue in all members of the GMC superfamily as Asn91, except for Pleurotus eryngii and Pleurotus pulmonarius AAO

during catalysis the non-covalently bound FAD cofactor is reduced by the substrate and subsequently reoxidized by molecular oxygen to yield hydrogen peroxide. The AAO substrate-binding pocket is located on the si side of the flavin ring and connected to the exposed surface by a hydrophobic substrate access channel. Two putative catalytic histidines, H502 and H546, are essential in AAO activity as a possible general bases in AAO catalysis. Residue F501, located near of cofactor and the putative catalytic histidines, is also involved in substrate oxidation by AAO

the ability of fungal aryl-alcohol oxidase (AAO) to oxidize 5-hydroxymethylfurfural (HMF) results in almost complete conversion into 2,5-formylfurancarboxylic acid (FFCA) in a few hours. The reaction starts with alcohol oxidation, yielding 2,5-diformylfuran (DFF), which is rapidly converted into FFCA by carbonyl oxidation, most probably without leaving the enzyme active site. AAO is combined with an unspecific peroxygenase, UPO, EC 1.11.2.1, from Agrocybe aegerita for full oxidative conversion of 5-hydroxymethylfurfural in an enzymatic cascade. This peroxygenase belongs to the recently described superfamily of hemethiolate peroxidases, and is capable of incorporating peroxide-borne oxygen into diverse substrate molecules. In contrast to AAO, the UPO reaction starts with oxidation of the HMF carbonyl group, yielding 2,5-hydroxymethylfurancarboxylic, which is converted into 2,5-formylfurancarboxylic acid and some 2,5-furandicarboxylic acid

the enzyme shows a T-shaped stacking interaction between the Tyr92 side chain and the alcohol substrate at the catalytically competent position for concerted hydride and proton transfers. Bi-substrate kinetics analysis reveals that reactions with 3-chloro- or 3-fluorobenzyl alcohols (halogen substituents) proceed via a ping-pong mechanism. But mono- and dimethoxylated substituents (in 4-methoxybenzyl and 3,4-dimethoxybenzyl alcohols) alter the mechanism and a ternary complex is formed.
