Target type: molecularfunction
Catalysis of the reaction: phenylacetaldehyde + NAD+ + H2O = phenylacetate + NADH + H+. [EC:1.2.1.39]
Phenylacetaldehyde dehydrogenase activity is a crucial enzymatic function involved in the metabolism of aromatic compounds, particularly those containing the phenyl group. This activity catalyzes the oxidation of phenylacetaldehyde, a volatile organic compound, to phenylacetic acid. This transformation is significant for several biological processes, including:
1. **Detoxification:** Phenylacetaldehyde is a toxic compound that can be generated by various metabolic pathways. Phenylacetaldehyde dehydrogenase plays a key role in eliminating this toxic compound by converting it into the less harmful phenylacetic acid.
2. **Aromatic Compound Degradation:** Phenylacetaldehyde dehydrogenase is part of the pathway responsible for breaking down aromatic compounds, which are found in many natural products and environmental pollutants. This pathway is essential for the detoxification and utilization of these compounds.
3. **Biosynthesis of Secondary Metabolites:** Phenylacetic acid, the product of phenylacetaldehyde dehydrogenase activity, serves as a precursor for the biosynthesis of various secondary metabolites, including plant hormones and antimicrobial compounds.
The enzyme responsible for this activity, phenylacetaldehyde dehydrogenase, belongs to the aldehyde dehydrogenase family. These enzymes typically utilize NAD+ or NADP+ as cofactors to catalyze the oxidation of aldehydes to their corresponding carboxylic acids.
Phenylacetaldehyde dehydrogenase activity is found in various organisms, including bacteria, fungi, plants, and animals. Its specific role and importance vary depending on the organism and its metabolic pathways.'
