phenylacetaldehyde + NAD+ + H2O = phenylacetate + NADH + 2 H+
sequential reaction mechanism in which NAD+ serves as both the leading substrate and homotropic allosteric activator, catalytic mechanism involving E169, E267, and C301, overview. The catalytic Glu has two conformations: a passive conformer that tucks away to allow hydride transfer to the nicotinamide ring, and an active conformer that abstracts a proton from the thioester-deacylating water

physiological function
additional information
malfunction
deletion of feaB gene results in increased desired aromatic compounds with decreased by-products. 2-Phenylethanol is not degraded by a feaB-deficient strain
malfunction
-
disruption of the endogenous phenylacetaldehyde dehydrogenase gene shuts off 4-hydroxyphenylacetate production and improves the production of tyrosol as a sole product
metabolism
-
FeaB plays a major role in the formation of 4-hydroxyphenylacetate
metabolism
the enzyme catalyzes a step in the styrene catabolic pathway of Pseudomonas putida
metabolism
two distinct enzymes are involved in the oxidation of phenylacetaldehyde to phenylacetate, an aldehyde:ferredoxin oxidoreductase (AOR) and a phenylacetaldehyde dehydrogenase (PDH). PDH is the primary enzyme during anaerobic phenylalanine degradation, whereas AOR is not essential for the metabolic pathway and exhibits probably a function as a detoxifying enzyme if high aldehyde concentrations accumulate in the cytoplasm, which would lead to substrate inhibition of PDH

additional information
Mg2+
the enzyme includes both an activating and inhibitory metal binding site in the catalytic mechanism of NPADH. The activating divalent metal binding site may be best described as the direct interaction of the metal ion with the pyrophosphate linkage joining the nicotinamide mononucleotide and adenosine mononucleotide components of the pyridine nucleotide structure. A second mononuclear metal binding site, occupied by Mg2+ is detected in this structure. The Mg2+ in this site assumes a roughly octahedral geometry and is coordinated by the backbone carbonyl oxygens of Val40, Asp109, Glu196, and Val345, as well as a monodentate interaction with a carboxylate oxygen of Asp109. The sixth ligand is a crystallographically resolved water molecule

NADH
product inhibition, competitive binding of NAD+. For many aldehyde dehydrogenases, NADH binds competitively with NAD+ and forms a nonproductive dead-end complex during catalysis. In the absence of styrene monooxygenase reductase, which regenerates NAD+ from NADH in the first step of styrene catabolism, NPADH is inhibited by a ternary complex involving NADH, product, and phenylacetaldehyde, substrate
PMSF
inactivates NPADH, presumably by modifying the active site cysteine
Pyridine nucleotides
titrations of NPADH with NADž and NADH are evaluated to estimate the binding affinities of the oxidized and reduced pyridine nucleotides under equilibrium conditions. Mg2+ is included in these studies

the oligomerization domains of all four subunits form the core of PADH and are responsible not only for the effective dimerization observed within the homotetramer, but also for the association of these dimers to form the tetramer. Each 496 amino acid PADH subunit consists of three domains: an N-terminal NADž-binding domain (residues 1-130 and 159-269), a catalytic domain (residues 270-471), and an oligomerization domain (131-158 and 472-496). The enzyme has a unique set of intersubunit interactions and active site tunnel for substrate entrance. Each oligomerization domain of NPADH contains a six-residue insertion that extends this loop over the substrate entrance tunnel of a neighboring subunit, thereby obstructing the active site of the adjacent subunit. This feature might be an important factor in the homotropic activation and product inhibition mechanisms. The substrate channel of NPADH is narrower and lined with more aromatic residues, which include Phe170, Phe295, Phe466, and Trp177, suggesting a means for enhancing substrate specificity
